Available in PDF, EPUB and Kindle. Book excerpt: Metal-semiconductor nanostructures represent an important new class of materials employed in designing advanced optoelectronic and nanophotonic devices, such as plasmonic nanolasers, plasmon-enhanced light-emitting diodes and solar cells, plasmonic emitters of single photons, and quantum devices operating in infrared and terahertz domains. The combination of surface plasmon resonances in conducting structures, providing strong concentration of an electromagnetic optical field nearby, with sharp optical resonances in semiconductors, which are highly sensitive to external electromagnetic fields, creates a platform to control light on the nanoscale. The design of the composite metal-semiconductor system imposes the consideration of both the plasmonic resonances in metal and the optical transitions in semiconductors - a key issue being their resonant interaction providing a coupling regime. In this book the reader will find descriptions of electrodynamics of conducting structures, quantum physics of semiconductor nanostructures, and guidelines for advanced engineering of metal-semiconductor composites. These constituents form together the physical basics of the metal-semiconductor plasmonics, underlying many effective practical applications. The list of covered topics also includes the review of recent results, such as the achievement of a strong coupling regime, and the preservation of non-classical statistics of photons in plasmonic cavities combined with semiconductor nanostructures.

Download or read book Exciton Plasmon Interactions in Metal Semiconductor Nanostructures written by Yikuan Wang and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, the use of surface plasmons (SPs) of noble metal nano-particles to control light emission on the nanometer scale has increased rapidly, due to their field enhancement and other special properties. With this boom in physics, chemistry, biomedical science and engineering has also come a rise in the need for understanding the dynamics of light emission in these systems. Traditional photoluminescence spectrum only gives limited information on quantum dot emission under SP resonances. This book, therefore, uses modern Time-Correlated Single Photon Counting technique and other approaches to study SPs in nanoparticle arrays, and their effects on semiconductor quantum dot emission. The observed SP resonances in metal nano-disc arrays enhances the CdSe/ZnS (core/shell) quantum dot emission in a way that is dependent on dipole emission angle and photon polarization, which is fully explained by quantum electrodynamics. This fundamental finding could be used to control the light emission in plasmonic device applications.

Book excerpt: Current developments in optical technologies are being directed toward nanoscale devices with subwavelength dimensions, in which photons are manipulated on the nanoscale. Although light is clearly the fastest means to send information to and from the nanoscale, there is a fundamental incompatibility between light at the microscale and devices and processes at the nanoscale. Nanostructured metals which support surface plasmon modes can concentrate electromagnetic (EM) fields to a small fraction of a wavelength while enhancing local field strengths by several orders of magnitude. For this reason, plasmonic nanostructures can serve as optical couplers across the nano–micro interface: metal–dielectric and metal–semiconductor nanostructures can act as optical nanoantennae and enhance light matter coupling in nanoscale devices. This book describes how one can fully integrate plasmonic nanostructures into dielectric, semiconductor, and molecular photonic devices, for guiding photons across the nano–micro interface and for detecting molecules with unsurpassed sensitivity.·Nanophotonics and Nanoplasmonics·Metamaterials and negative-index materials·Plasmon-enhanced sensing and spectroscopy·Imaging and sensing on the nanoscale·Metal Optics

Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first detailed description, including both theoretical aspects and experimental methods, of the interaction of rare-earth ions with surface plasmon polariton from the point of view of collective plasmon-photon interactions via resonance modes (metal nanoparticles or nanostructure arrays) with quantum emitters (rare-earth ions). These interactions are of particular interest for applications to optical telecommunications, optical displays, and laser solid state technologies. Thus, our main goal is to give a more precise overview of the rapidly emerging field of nanophotonics by means of the study of the quantum properties of light interaction with matter at the nanoscale. In this way, collective plasmon-modes in a gain medium result from the interaction/coupling between a quantum emitter (created by rare-earth ions) with a metallic surface, inducing different effects such as the polarization of the metal electrons (so-called surface plasmon polariton - SPP), a field enhancement sustained by resonance coupling, or transfer of energy due to non-resonant coupling between the metallic nanostructure and the optically active surrounding medium. These effects counteract the absorption losses in the metal to enhance luminescence properties or even to control the polarization and phase of quantum emitters. The engineering of plasmons/SPP in gain media constitutes a new field in nanophotonics science with a tremendous technological potential in integrated optics/photonics at the nanoscale based on the control of quantum effects. This book will be an essential tool for scientists, engineers, and graduate and undergraduate students interested not only in a new frontier of fundamental physics, but also in the realization of nanophotonic devices for optical telecommunication.

Download or read book Plasmonic Effect on Exciton and Multiexciton Dynamics of Quantum Dots Near Metal Nanostructures written by Swayandipta Dey and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific progress has resulted in the development of sophisticated hybrid nanostructures composed of semiconductor nanocrystals (quantum dots, QDs) and metal nanoparticles (MNPs). These hybrid structures open up new possibilities for developing next generation nanoscale optoelectronic devices that combine the best attributes of each component material.The optical response of MNPs is dominated by surface plasmon resonances which create large local electromagnetic field enhancements. When coupled to surrounding semiconductor components, the enhanced local electric field results in strong absorption/emission, alteration in emission decay rates, enhancement in exciton emission and other interesting non-linear effects (multiphoton generation). Although hybrid nanostructures are poised to be utilized in a variety of applications, serious hurdles for the design of new devices still remain. These difficulties largely result from a poor understanding of how the structural components interact at the nanoscale. These synergetic interactions strongly depend on the exact composition and geometry of the structure, and therefore, a quantitative comparison between theory and experiment is often difficult to achieve. My dissertation work primarily focuses on paving a bridge between the experimental and theoretical studies and the mechanisms involved in exciton and multiexciton emission dynamics of single QDs in presence of plasmonic nanostructures by careful consideration of different parameters which significantly affect the interaction between these nanoparticles at a single particle level.

Book excerpt: This thesis presents a comprehensive theoretical description of classical and quantum aspects of plasmonics in three and two dimensions, and also in transdimensional systems containing elements with different dimensionalities. It focuses on the theoretical understanding of the salient features of plasmons in nanosystems as well as on the multifaceted aspects of plasmon-enhanced light–matter interactions at the nanometer scale. Special emphasis is given to the modeling of nonclassical behavior across the transition regime bridging the classical and the quantum domains. The research presented in this dissertation provides useful tools for understanding surface plasmons in various two- and three-dimensional nanostructures, as well as quantum mechanical effects in their response and their joint impact on light–matter interactions at the extreme nanoscale. These contributions constitute novel and solid advancements in the research field of plasmonics and nanophotonics that will help guide future experimental investigations in the blossoming field of nanophotonics, and also facilitate the design of the next generation of truly nanoscale nanophotonic devices.

This book was released on 2014 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor nanostructures are ideal candidates for non-metallic plasmonic materials that operate in the near- to mid-infrared range. In contrast to metal nanostructures, semiconductor nanomaterials have the advantage of possessing tunable carrier concentrations. However, unlike metal nanoparticles which are already widely exploited in plasmonics, little is known about the shape-dependent localized surface plasmon resonances (LSPRs) and near-field electromagnetic behavior of semiconductor nanocrystals. Moreover, a major challenge in the fabrication of plasmonic semiconductor nanomaterials is the ability to control LSPRs by independently varying the size, shape, and carrier density of the nanocrystal. In this dissertation, I describe colloidal synthetic methods for fabricating shaped Cu2-xS nanocrystals in which the morphology and stoichiometry of Cu2-xS can be modulated. These shaped Cu2-xS nanocrystals are used to observe the plasmon response for specific LSPR modes. Specifically, I discuss the plasmon response of Cu2-xS nanodisks as a model nanocrystal system. I demonstrate that LSPR wavelength can be tuned by independently varying the aspect-ratio of the disk and the overall carrier density of the nanocrystal. Increased carrier density in Cu2-xS occurs with oxidation and the formation of copper vacancies, an effect which can be suppressed by carrying out synthesis under an inert atmosphere. Using post-synthetic oxidation, Cu2-xS nanodisks achieve a critical carrier density beyond which the nanocrystals undergo an irreversible phase change, which limits tuning capability. To circumvent this, I use a solvothermal process to generate nanodisks with different crystal phases that enable carrier densities beyond this critical limit. This dissertation also explores the differences in near-field coupling between Cu2-xS nanodisks. These experiments were carried out on self-assembled two-dimensional nanodisk arrays. Varying nanodisk orientation produces a dramatic change in the magnitude and polarization direction of the local field generated by LSPR excitation. Moreover, plasmonic coupling is only observed for Cu2-xS phases that possess carrier densities above a critical value. Overall, this dissertation provides new methods for tuning the plasmonic response of semiconductor nanocrystals by controlling size, shape, and carrier density. It also demonstrates new strategies for designing electromagnetic junctions or coupled plasmonic architectures that operate in the infrared using nanocrystals as building blocks.

In addition to the above, the surface plasmon resonances can be controlled by adjusting the size, shape, periodicity, and materials' nature. All these optical properties can enable a great number of applications, such as biosensors, optical modulators, photodetectors, and photovoltaic devices. This book is intended for a broad audience and provides an overview of some of the fundamental knowledges and applications of nanoplasmonics.
