▎ 摘　　要

NOVELTY - The radiation detector (106) comprises a bulk semiconductor crystal that has indium antimonide, cadmium telluride, or cadmium zinc telluride. The electrical contacts are coupled to two facets of the bulk semiconductor crystal. A bias circuit (110) is electrically coupled to the bulk semiconductor crystal through the electrical contacts. A terahertz electromagnetic wave receiver (114) is positioned to detect terahertz radiation emitted by the bulk semiconductor crystal. A thermoelectric cooler is positioned within the hermetic enclosure and thermally coupled to the bulk semiconductor crystal. A wheat sink is positioned outside the hermetic enclosure and thermally coupled to the thermoelectric cooler through the hermetic enclosure. USE - Wireless gamma or hard X-ray radiation detector for use in a gamma or hard x-ray detector system (claimed) to detect gamma or hard X-ray radiation without photocurrent or carrier transport detection mechanism in the bulk semiconductor crystal. ADVANTAGE - The detector eliminates or reduces adverse plasmonic effects that can arise from use of metal contacts at a surface or surfaces of the bulk semiconductor crystal, and reduce or eliminate adverse thermal and electrical effects, such as low bulk resistance and breakdown which can lead to electrical shorts. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a wireless gamma or hard X-ray radiation detector. 106Detector 108Power Supply 110Bias Circuit 114Wave Receiver 118Switch
