Abstract
In this paper, the effects of the trapping of electrons and holes on the performance of gallium arsenide x-(gamma) ray detectors are analyzed. Starting from the experimental spectra acquired with state of the art GaAs detectors, it is shown how much the existing modeling of the charge trapping can explain the data and predict the observed excess noise due to the trapping. An analysis made with Monte-Carlo simulations has been carried out and compared with the experiments. The relationship between the fraction of the trapped charge and the energy resolution of the detector has been determined and analyzed.
