摘要：

We show a method for obtaining excellent spectroscopic performance for CdZnTe gamma- and X-ray detectors with segmented readout. Best spectroscopic performance is obtained by tuning the electron trapping in the detector material to obtain optimum compensation for the incomplete charge collection caused by the large amount of hole trapping. For a CdZnTe detector with pad segmentation, we obtain for Co-57 a photopeak resolution of better than 3.5% FWHM with a peak-to-valley ratio of similar to 100/1. (C) 1999 Elsevier Science B.V.
