This book provides in-depth knowledge about the fundamental physical properties of bulk and low dimensional semiconductors (LDS). It also explains their applications to optoelectronic devices. The book incorporates two major themes. The first theme, starts from the fundamental principles governing the classification of solids according to their electronic properties and leads to a detailed analysis of electronic band structure and electronic transport in solids. It then focuses on the electronic transport and optical properties of semiconductor compounds, size quantization and the analysis of abrupt p-n junctions where a full analysis of the fundamental properties of intrinsic and doped semiconductors is given. The second theme is device-oriented. It aims to provide the reader with understanding of the design, fabrication and operation of optoelectronic devices based on novel semiconductor materials, such as high-speed photo detectors, light emitting diodes, multi-mode and single-mode lasers and high efficiency solar cells.

Optoelectronics have become a vital part of our lives and today's technology. Optoelectronic devices such as light emitting diodes, semiconductor lasers, photodetectors and solar cells operate using interactions between electrons and photons. Today optoelectronic devices take place in a vast range of applications from fiber-optic communication to medical applications and remote sensing systems. Optoelectronic devices are based on semiconductors. Using modern growth techniques, it is possible to discover novel semiconductors, therefore, the operation wavelengths of optoelectronic devices cover UV to MIR regions of the electromagnetic waves. The unique properties, their controllable electrical conductivity and tailoring their bandgaps, make semiconductors indispensable in optoelectronic technology. Furthermore, using advanced lithographic techniques, it is possible to decrease the size of the semiconductors to nanometer scale that leads to fabricating high capacity, fast, high efficient, compact, high sensitive optoelectronic devices. Optoelectronics have been playing an increasingly important role in our lives since the discovery of observation light emission from a GaAs-based p-n junction and today highly efficient LEDs illuminate the world as a light source of the 21st century.

To understand how optoelectronic devices operate, it is necessary to have knowledge on semiconductor physics, electronic transport and optical processes in semiconductors. Therefore, first three chapters provide knowledge on the basics of these topics. All optoelectronic devices are based on a p-n junction. Chapter 4 gives a deep insight into physics of p-n junctions. The rest of the book investigates solar cells, photodetectors, LEDs and semiconductor lasers.

The target of this book is physics students, electronic engineers and researchers who are interested in semiconductors physics and applications, designing optoelectronic devices. We have written the chapters to allow readers, who are new to the subjects, to comprehend the fundamental concepts in optoelectronics.
