摘要：

The coplanar-grid charge sensing technique provides a method for improving the spectral response of gamma-ray detectors based on compound semiconductors, which typically have poor charge transport properties. The technique functions by effectively modifying the charge induction characteristics of the detector such that the dependence of detector signal on the depth of radiation interaction is minimized. The effectiveness of this technique however can be compromised by non-uniform charge induction characteristics across the detector. This paper examines such non-uniformity due to fringe effects near the detector edges. Alternate electrode configurations are studied that provide effective compensation for such effects. Results from experimental measurements and computer simulations are presented.
