Fe-Doped High Purity GaAs as a Room Temperature Gamma-Ray Spectrometric Detector

Abstract

Fe-doped high purity GaAs crystals have been grown using a vertical-type liquid-phase epitaxial technique and have been studied as room temperature gamma-ray spectrometric detectors for nuclear fuel safeguards. To improve the detector gamma-ray counting efficiency, a double-epitaxial-layer detector was studied.
