Note Editore

Although elemental semiconductors such as silicon and germanium are standard for energy dispersive spectroscopy in the laboratory, their use for an increasing range of applications is becoming marginalized by their physical limitations, namely the need for ancillary cooling, their modest stopping powers, and radiation intolerance. Compound semiconductors, on the other hand, encompass such a wide range of physical and electronic properties that they have become viable competitors in a number of applications. Compound Semiconductor Radiation Detectors is a consolidated source of information on all aspects of the use of compound semiconductors for radiation detection and measurement. Serious Competitors to Germanium and Silicon Radiation Detectors Wide-gap compound semiconductors offer the ability to operate in a range of hostile thermal and radiation environments while still maintaining sub-keV spectral resolution at X-ray wavelengths. Narrow-gap materials offer the potential of exceeding the spectral resolution of germanium by a factor of three. However, while compound semiconductors are routinely used at infrared and optical wavelengths, their development in other wavebands has been plagued by material and fabrication problems. So far, only a few have evolved sufficiently to produce commercial detection systems. From Crystal Growth to Spectroscopic Performance Bringing together information scattered across many disciplines, this book summarizes the current status of research in compound semiconductor radiation detectors. It examines the properties, growth, and characterization of compound semiconductors as well as the fabrication of radiation sensors, with particular emphasis on the X- and gamma-ray regimes. It explores the limitations of compound semiconductors and discusses current efforts to improve spectral performances, pointing to where future discoveries may lie. A timely resource for the established researcher, this book serves as a comprehensive and illustrated reference on material science, crystal growth, metrology, detector physics, and spectroscopy. It can also be used as a textbook for those new to the field of compound semiconductors and their application to radiation detection and measurement.

Autore

Dr. Alan Owens has an undergraduate degree in Physics and Physical Electronics and a Doctorate from the University of Durham, United Kingdom, in Astrophysics. He spent 30 years in the design and construction of novel detection systems for X- and gamma-ray astronomy and is currently a staff physicist at the European Space Agency, involved in the development and exploitation of new technologies for space applications. Much of this work revolves around compound semiconductors for radiation detection and measurement, which by its very nature involves materials and systems at a low level of maturity. Consequently, he has been involved in all aspects of a systematic and long-term program on material assessment, production, processing, detector fabrication, and characterization for a large number of compound semiconductors.
