摘要：

The authors have developed a theoretical model for the response of a coplanar grid semiconductor detector to hard x- and gamma-ray radiation. Carrier drift trajectories were obtained by solving the coupled dynamical equations for carriers driven by electrostatic fields of the coplanar grid configuration. The pulse spectra calculated by summing the individual contributions for all carriers are compared to experimental results for a large volume optimized cadmium zinc telluride coplanar grid detector and good agreement is obtained.
