Nuclear Experimental Technique


The characteristics of detectors of soft-X and γ rays based on high-purity epitaxial GaAs layers are discussed. The characteristics of detectors with different rectifying contacts are compared, that is, those with a Schottky barrier and a pn junction. The spectral characteristics of the manufactured detectors that were obtained under the irradiation by 57Co and 241Am sources at different bias voltages and in a photovoltaic mode and the simulation results using the Geant 3.21 software package are presented.
