Abstract :
Although there has been significant recent progress in the development of CdTe and CdZnTe radiation detectors, these materials are still plagued by charge trapping and recombination problems. Recent work has shown that fabrication of arrays with small anodes can overcome these problems to some extent. The purpose of this simulation study was to investigate this small anode effect in relatively large strip detectors of various geometries
