Nitride semiconductors have tremendous potential, particularly in visible and ultraviolent optoelectronics. This book describes the physics of nitride-based materials and related devices. Its goal is to provide graduate students and young researchers with a rapid introduction to this burgeoning field. It contains tutorial-style chapters commissioned from some of the very best experts from academia and industry. The book addresses all aspects arising from the dual challenges of achieving high-quality, single crystal material and engineering optoelectronic devices. In the first chapters, the...

The study of electrons and holes confined to two, one and even zero dimensions has uncovered a rich variety of new physics and applications. This book describes the interaction between these confined carriers and the optic and acoustic phonons within and around the confined regions. Phonons provide the principal channel of energy transfer between the carriers and their surroundings and also the main restriction to their room temperature mobility. But they have many other roles; they provide for example an essential feature of the operation of the quantum cascade laser. Since their moment at...

At the heart of much current technology, including fiber-optic communications, optoelectronic devices outperform those based on conventional semiconductors and are likely to be essential in future computers. This book provides a basic understanding of the physical phenomena involved and is ideal for graduate students and engineers interested in designing new materials, devices and applications in optoelectronics. The book gives simple quantum mechanical explanations of important optical processes; it describes band-to-band, intersubband and excitonic absorption and recombination in bulk,...

The book addresses issues associated with physics and technology of injection lasers based on self-organized quantum dots. Fundamental and technological aspects of quantum dot edge-emitting lasers and VCSELs, their current status and future prospects are summarized and reviewed. Basic principles of QD formation using self-organization phenomena are reviewed. Structural and optical properties of self-organized QDs are considered with a number of examples in different material systems. Recent achievements in controlling the QD properties including the effects of vertical stacking, changing the...

This book focuses on the remarkable recent advances in understanding low pressure radio frequency glow discharges. It explains the basic analytical theory, plasma physics, and plasma diagnostics, before proceeding to the details of the etching process.
