In order to simulate the low-energy tail in the response function of a Schottky CdTe detector, which is a high-resolution room temperature X- or γ-ray spectrometer, we introduced the effect of a nonuniform electric field within the detector to the response function by a Monte Carlo calculation using the EGS5 code. The simulated response functions were compared with measurements for γ-rays from 109Cd, 241Am, 133Ba, and 57Co sources. The present method successfully reproduced the low-energy tail due to the charge carrier trapping effect, while the conventional model assuming a uniform electric field underestimated the low-energy tail significantly, particularly for higher energy γ-rays.
