摘要：
We have developed a Monte Carlo simulator for semi-insulating GaAs detectors which gives the energy spectra of x-ray radiations. The simulated spectra are analyzed in terms of: shaping time, trapping properties of the material, and applied reverse voltage. The main features of the spectra as well as the associated charge collection efficiency and the energy resolution of the photoelectric peak are interpreted in physical terms for the whole range of applied voltages covering under- and over-depleted conditions. The results of the simulations provide a general interpretation scheme which is satisfactorily tested with experimental results.
