Principles of Surface Enhanced Raman Spectroscopy Book Review:

SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) Gives a comprehensive summary of the underlying physical concepts around SERS Provides a detailed analysis of plasmons and plasmonics

Tip Enhanced Raman Spectroscopy for Nanoelectronics Book Review:

This dissertation focuses on the application of Tip-Enhanced Raman spectroscopy (TERS) to non-transparent and non-conductive samples, allowing for the optical characterization of nanoelectronic devices. As such, nano-crystals are analyzed as a model system for the investigation of chemical and structural properties. Furthermore, a novel method for mapping the refractive index of materials with nanometer resolution is presented. The technological progress of electronics through miniaturization has reached the nanoscale while new materials with high performance and functional properties gain importance. Quality control and the scientific understanding of size effects in electronic nanostructures are required more than ever to consolidate existing technologies and to determine scaling limits of new materials. Conventional techniques, including scanning electron and scanning probe microscopy, provide topographic information but only very limited chemical information to analyze the physical properties of nanomaterials. Chemical and structural sensitivity is available by Raman or infrared spectroscopy, but with a spatial resolution limited to the microscale by the diffraction limit of light. TERS combines the virtues of scanning probe microscopy with those of optical spectroscopy to overcome the diffraction limit through the excitation of surface plasmons on a scanning probe tip to confine light to nanometers. In this work, a TERS system was installed to operate on opaque samples by employing optical side access. TERS probes were fabricated by electrochemical etching and operated in scanning tunneling microscopy and atomic force microscopy with quartz tuning forks to enable scanning on various surfaces. TERS was then applied to ferroelectric lead titanate nano-crystals on a platinized silicon substrate as a model system for nanostructured, charge-based memory devices at the onset of finite size effects.

Comprehensive Nanoscience and Technology Book Review:

From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.

Spectroelectrochemistry Book Review:

The intention of this monograph has been to assimilate key practical and theoretical aspects of those spectroelectrochemical techniques likely to become routine aids to electrochemical research and analysis. Many new methods for interphasial studies have been and are being developed. Accordingly, this book is restricted in scope primarily to in situ methods for studying metal! electrolyte or semiconductor! electrolyte systems; moreover, it is far from inclusive of the spectroelectrochemical techniques that have been devised. However, it is hoped that the practical descriptions provided are sufficiently explicit to encourage and enable the newcomer to establish the experimental facilities needed for a particular problem. The chapters in this text have been written by international authorities in their particular specialties. Each chapter is broadly organized to review the origins and historical background of the field, to provide sufficiently detailed theory for graduate student comprehension, to describe the practical design and experimental methodology, and to detail some representative application examples. Since publication of Volume 9 of the Advances in Electrochemistry and Electrochemical Engineering series (1973), a volume devoted specifically to spectroelectrochemistry, there has been unabated growth of these fields. A number of international symposia-such as those held at Snowmass, Colorado, in 1978, the proceedings of which were published by North-Holland (1980); at Logan, Utah in 1982, published by Elsevier (1983); or at the Fritz Haber Institute in 1986-have served as forums for the discussion of nontraditional methods to study interphases and as means for the dissemination of a diversity of specialist research papers.

The topical structure of this new edition is now subdivided into four parts. The first treats the fundamentals of the instrumentation for infrared and Raman imaging and mapping and an overview on the chemometric tools for image analysis. The second part describes a wide varie-ty of applications ranging from biomedical via food, agriculture and plants to polymers and pharmaceuticals. This is followed by a description of imaging techniques operating beyond the diffraction limit, while the final part covers special methodical developments and their utility in specific fields. With its many valuable practical tips, this is a must-have overview for researchers in academic and industrial laboratories wishing to obtain reliable results with this method.

Interpreting High Resolution Tip Enhanced Raman Spectroscopy Images Book Review:

Raman spectroscopy is one of the fundamental techniques in chemical characterization. It measures the amount of photons and their frequency shifts scattered by the molecule under a given laser beam. The frequency shifts originate from the molecule's vibrations, which are determined by its microscopic structure. Thus, a Raman spectrum is often regarded as the molecule's "fingerprint". When the molecule is placed on a noble metal surface with some curvature, the Raman signals are greatly enhanced by the plasmonic near field at the surface. This technique is called "surface- enhanced Raman spectroscopy", or SERS. Because of the significantly improved sensitivity relative to regular Raman scattering, SERS has grown into a widely popular tool for chemical research and practical applications. Moreover, the molecule-metal interaction that lies in the center of the mechanism of SERS has been a hot topic of fundamental research since its discovery and has led to many variants in the development of spectroscopic techniques. Tip-enhanced Raman spectroscopy (TERS) integrates the scanning probe microscopy and SERS. Similar to SERS, the enhancement of Raman scattering in TERS benefits from the inhomogeneous near field induced by the plasmonic resonance of the noble metal nanostructure. However, the TERS spectrum of a molecule is often found different than SERS, and it changes with the tip position. The combination of the chemical sensitivity and the spatial resolution makes TERS a promising technique for microscopic characterization. A comprehensive demonstration of these unique features is TERS imaging. A TERS image is a two-dimensional map of the Raman intensity at a certain frequency varying with the scanning tip. It exhibits a sub-nanometer resolution and is specific to the corresponding vibrational mode. TERS imaging is considered as a visualization of molecular vibrations and sets stage for a new way of understanding molecules. Therefore, it is necessary to develop theoretical interpretation of TERS images and their connections to the underlying molecular vibration. However, interpreting TERS images is challenging as the brightspot pattern does not always strictly align with the vibrating atoms and the signals are very sensitive to experimental conditions. In this dissertation, three major aspects of TERS theory are explored: the effect of the plasmonic near field electromagnetic mechanism), the plasmonic resonance inside a subnanometer cavity (gap plasmonics), and the quantum mechanical interactions between the molecule and the substrate (the chemical mechanism). In particular, the critical conditions of the near field to achieve atomic resolution are found. It is also illustrated that the locally integrated Raman polarizability density is the sub-molecular property probed by the confined near field in TERS. It provides an intuitive description of the TERS imaging mechanism, which is usually hidden in the self-consistent cycles of conventional calculations using the time-dependent density functional theory. The distinct feature of TERS is largely ascribed to the unique plasmonic properties of a sub-nanometer junction consisting of a flat metal substrate and an atomically sharp tip. At this length scale, atomistic electrodynamics is adopted to describe the nanostructure because it captures the microscopic structure and at the same time retains the efficiency of a classical model.To study the charge-transfer plasmon due to quantum tunneling, a Hirshfeld partitioning scheme is developed to distinguish the plasmonic resonances within and across the coupled nanoparticles. Furthermore, this dissertation presents the development of a new theoretical method to better describe the substrate-molecule coupling, namely, exact frozen density embedding. The method to obtain the response properties of a molecule is derived based on the exact frozen density embedding within the framework of time-dependent density functional theory. Finally, a polarizable frozen density embedding method is developed to include the polarization effect due to the presence of a metal nanoparticle. The development of these theoretical tools is potentially applicable to the studies of the electronic structures of a TERS system.

Expanding Tip Enhanced Raman Spectroscopy Book Review:

Through the use of alternative probe materials, specifically titanium nitride, the capabilities of Tip enhanced Raman spectroscopy (TERS) have been expanded to new environments, and through the study of the blinking phenomenon a greater understanding of its capabilities has been achieved. TERS is a powerful analytical technique for measuring surfaces on the nanoscale. It is capable of simultaneously providing well resolved topographical and chemical information from a sample surface, and has been previously shown to be capable of single molecule sensitivity. It is shown here that blinking of individual species of a miscible blend can be observed even in non-resonant, non-dilute polymer systems. This result affirms thermal diffusion as the primary diffusive mechanism driving blinking, allows us to infer the size of highly enhancing areas within a larger plasmonic structure, and acts as a potential stepping stone towards more quantitative measurements with more well defined probes. Improving upon the versatility of the technique, protected titanium nitride coated probes are demonstrated to not only provide enhancement, but to act as robust probes in aqueous environments and to allow for the plasmon resonance wavelength to be tuned based on deposition conditions. These two properties serve to expand the applicability of TERS; extending potential for in-situ biological measurements and allowing for use in a wider variety of laboratory conditions.

Extreme Photonics Applications Book Review:

"Extreme Photonics & Applications" arises from the 2008 NATO Advanced Study Institute in Laser Control & Monitoring in New Materials, Biomedicine, Environment, Security and Defense. Leading experts in the manipulation of light offered by recent advances in laser physics and nanoscience were invited to give lectures in their fields of expertise and participate in discussions on current research, applications and new directions. The sum of their contributions to this book is a primer for the state of scientific knowledge and the issues within the subject of photonics taken to the extreme frontiers: molding light at the ultra-finest scales, which represents the beginning of the end to limitations in optical science for the benefit of 21st Century technological societies. Laser light is an exquisite tool for physical and chemical research. Physicists have recently developed pulsed lasers with such short durations that one laser shot takes the time of one molecular vibration or one electron rotation in an atom, which makes it possible to observe their internal electronic structure, thereby enabling the study of physical processes and new chemical reactions. In parallel, advances in micro- and nano-structured photonic materials allow the precise manipulation of light on its natural scale of a wavelength. Photonic crystals, plasmons and related metamaterials - composed of subwavelength nanostructures - permit the manipulation of their dispersive properties and have allowed the experimental confirmation of bizarre new effects such as slow light and negative refraction. These advances open a vista on a new era in which it is possible to build lasers and engineer materials to control and use photons as precisely as it is already possible to do with electrons. http://www.photonics.uottawa.ca/nato-asi-2008/
