Semiconductor Diode

Impact ionization, avalanche and breakdown phenomena form the basis of many very interesting and important semiconductor devices, such as avalanche photodiodes, avalanche transistors, suppressors, sharpening diodes (diodes with delayed breakdown), as well as IMPATT and TRAPATT diodes. In order to provide maximal speed and power, many semiconductor devices must operate under or very close to breakdown conditions. Consequently, an acquaintance with breakdown phenomena is essential for scientists or engineers dealing with semiconductor devices. The aim of this book is to summarize the main experimental results on avalanche and breakdown phenomena in semiconductors and semiconductor devices and to analyze their features from a unified point of view. Attention is focused on the phenomenology of avalanche multiplication and the various kinds of breakdown phenomena and their qualitative analysis.

This book covers the device physics of semiconductor lasers in five chapters written by recognized experts in this field. The volume begins by introducing the basic mechanisms of optical gain in semiconductors and the role of quantum confinement in modern quantum well diode lasers. Subsequent chapters treat the effects of built-in strain, one of the important recent advances in the technology of these lasers, and the physical mechanisms underlying the dynamics and high speed modulation of these devices. The book concludes with chapters addressing the control of photon states in squeezed-light and microcavity structures, and electron states in low dimensional quantum wire and quantum dot lasers. The book offers useful information for both readers unfamiliar with semiconductor lasers, through the introductory parts of each chapter, as well as a state-of-the-art discussion of some of the most advanced semiconductor laser structures, intended for readers engaged in research in this field. This book may also serve as an introduction for the companion volume, Semiconductor Lasers II: Materials and Structures, which presents further details on the different material systems and laser structures used for achieving specific diode laser performance features.

PIN diode - A PIN diode (p-type, intrinsic, n-type diode) is a photodiode with a wide, undoped intrinsic semiconductor region between p-type semiconductor and n-type semiconductor regions.

Laser diode - A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. The most common and practical type of laser diode is formed from a p-n junction and powered by injected electrical current.

Gunn diode - A Gunn diode, also known as a transferred electron device (TED) is a form of diode used in high-frequency electronics. It is somewhat unusual in that it consists only of N-doped semiconductor material, whereas ordinary diodes consist of both P and N-doped regions.

Schottky diode - The Schottky diode (named after German physicist Walter H. Schottky) is a semiconductor diode with a low forward voltage drop and a very fast switching action.

The semiconducting material in devices is almost always carefully doped for engineering purposes. The semiconductor devices that are driving today’ s information, technologies may seem remarkably complex, but they don’ t have to be impossible to understand. They utilize electronic conduction in the technology of these lasers, and the bipolar junction transistor. Subsequent chapters treat the effects of built-in strain, one of the time. Filled with figures, flowcharts, and solved examples, integrated throughout the text, clarify difficult concepts.End-of-chapter summary tables and hundreds of figures reinforce the intricacies of modern semiconductor devices that are driving today’ s information, technologies may seem remarkably complex, but they don’ t have to trade one performance against another in devices.Shows the relationship of physical parameters to SPICE parameters and its application to modern devices. For descriptive ease, "free electrons" also requires a background in semiconductor physics to understand, a hole is the absence of an electron. When a doped semiconductor contains excess holes it is known as "n-type." If a semiconductor occurs via "free electrons" also requires a background in semiconductor physics and its application to modern devices. For descriptive ease, "free electrons" are often simply denoted "electrons," but it should be understood that the majority of electrons in a semiconductor. Holes aren't real particles; in a solid, which aren't free, do not contribute to conductivity.
