Germanium X-Ray Detectors

  • R. A. Sareen

Abstract

Methods of employing semiconductor materials to detect electromagnetic radiation, charged particles, and neutrons have been developed extensively during the last forty years. (1) Within this period, a particular semiconductor has been chosen for a specific application following extensive research and development. For example, the lithium drifted silicon (Si(Li)) detector(2) of a particular shape and size has been the preferred choice for detecting low energy x rays and has helped to promote the science of microanalysis on electron microscopes and other excitation sources. These include x-ray excited fluorescence systems, diffractometers, synchrotrons and particle accelerators. Within the last five years (3,4) it has become clear that germanium is capable of rivaling silicon with certain advantages. This presentation reviews the development of these germanium detectors as devices for high resolution energy dispersive x-ray spectroscopy and compares their performance with silicon.
