Semiconductors for room-temperature radiation detector applications 2

The purpose of the symposium was to provide a forum for presenting and evaluating the most recent results on semiconductor radiation detectors for use in the energy range of a few eV to about 5 MeV. The primary emphasis of the papers was on developing semiconductor X-ray and gamma-ray detectors and imagers which combine the advantages of room-temperature operation with the excellent energy resolution of cryogenically cooled spectrometers. By eliminating the cryogen, new radiation-sensing instruments, such as spectrometers and imagers, can be manufactured that are portable, easy to operate, and relatively maintenance-free. The symposium was organized into technical sessions on cadmium zinc telluride, mercuric iodide, imagers, fabrication and processing, device modeling, II-VI materials (including a joint session with the symposium on infrared materials and technology), cadmium telluride, vapor-deposited materials, lead iodide, group IV materials, and radiation damage. The primary emphasis however, was clearly on cadmium zinc telluride (CZT), as this material has resulted in significant progress in the development of single detectors, imagers, and systems appropriate for a number of applications. Separate abstracts were prepared for most papers in the volume.
