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.

In recent years, the physics community has experienced a revival of interest in spin effects in solid state systems. On one hand, the solid state systems, particularly, semiconductors and semiconductor nanosystems, allow us to perform benchtop studies of quantum and relativistic phenomena. On the other hand, this interest is supported by the prospects of realizing spin-based electronics, where the electron or nuclear spins may play a role of quantum or classical information carriers. This book looks in detail at the physics of interacting systems of electron and nuclear spins in semiconductors, with particular emphasis on low-dimensional structures. These two spin systems naturally appear in practically all widespread semiconductor compounds. The hyperfine interaction of the charge carriers and nuclear spins is particularly prominent in nanosystems due to the localization of the charge carriers, and gives rise to spin exchange between these two systems and a whole range of beautiful and complex physics of manybody and nonlinear systems. As a result, understanding of the intertwined spin systems of electrons and nuclei is crucial for in-depth studying and controlling the spin phenomena in semiconductors. The book addresses a number of the most prominent effects taking place in semiconductor nanosystems including hyperfine interaction, nuclear magnetic resonance, dynamical nuclear polarization, spin-Faraday and spin-Kerr effects, processes of electron spin decoherence and relaxation, effects of electron spin precession mode-locking and frequency focussing, as well as fluctuations of electron and nuclear spins.

Plasmonics is a rapidly developing field that combines fundamental research and applications ranging from areas such as physics to engineering, chemistry, biology, medicine, food sciences, and the environmental sciences. Plasmonics appeared in the 1950s with the discovery of surface plasmon polaritons. Plasmonics then went through a novel propulsion in the mid-1970s, when surface-enhanced Raman scattering was discovered. Nevertheless, it is in this last decade that a very significant explosion of plasmonics and its applications has occurred. Thus, this book provides a snapshot of the current advances in these various areas of plasmonics and its applications, such as engineering, sensing, surface-enhanced fluorescence, catalysis, and photovoltaic devices.

Noble metal nanoparticles and two-dimensional (2D) transition metal dichalcogenide (TMD) crystals offer unique optical and electronic properties that include strong exciton binding, spin-orbital coupling, and localized surface plasmon resonance. Controlling these properties at high spatiotemporal resolution can support emerging optoelectronic coupling and enhanced optical features. Excitation dynamics of these optical properties on physicochemically bonded mono- and few-layer TMD crystals with metal nanocrystals and two overlapping spherical metal nanocrystals were examined by concurrently (i) DDA simulations and (ii) far-field optical transmission UV-vis spectroscopic measurements. Initially, a novel and scalable method to unsettle van der Waals bonds in bulk TMDs to prepare mono- and few-layer crystals was performed. Examination of the solution-based and electrochemical deposition of metal nanocrystals on 2D TMD crystals, comparing their optical, electronic, and optoelectronic characteristics was accomplished via characterization methods. Subsequently, DDA simulations for noble metal - semiconductor nanocrystal and noble metal - noble metal nanocrystal heterostructures analyzed the effects of metal type, geometry, and orientation for the predefined nanoantennae parameters. Results from these computational and experimental optical spectra demonstrate promising percent error difference, in which distinguished quantitative effects of 2D TMDs crystals - metal nanocrystals and metal nanocrystals - metal nanocrystals facilitated optoelectronic activity in the UV-Vis-NIR region. New experimental and theoretical insights into energy conversion interactions between coupled plasmonic and excitonic materials spanning the optical regimes were established towards their applications in optoelectronic and biological engineering platforms.

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.
