Spectroscopy And Optical Properties Of Semiconductors

This book investigates and describes the spectroscopies and optical properties of semiconductor bulk material, as well as their micro- and nanostructures. Such structures include quantum wells, superlattices, quantum wires and quantum dots. Traditional optical studies have focused on macroscopic optical constants and quantum mechanical theory, but our work investigates and details further the electrical states and their optical transitions, reflective and absorption spectra, luminescence and radiative recombination, photothermal ionization, magneto-optical effects, cyclotron resonance, and Raman scattering in these advanced semiconductor systems.While highlighting key contributions by the international scientific community in the field, this book emphasises on the new developments and results from the past 30 to 40 years — primarily our own work. Of special interest are the exciton-polaritons in ZnO quantum wires, high-density polaritons in micro-cavities, and resulting phenomena such as room-temperature Bose-Einstein condensation (BEC)-like states, phonon-polaritons, quantum chaos in impurity electrons, and quantum effects in single quantum dots.These represent some of the most fascinating and significant phenomena in solid-state physics today, continuing to drive active research and new discoveries well into the future. We believe that this book will serve as a meaningful textbook for graduate students, and reference book for academic researchers and industry professionals engaged in semiconductor and optical physics.
