I. %J Tekhnologiya i Konstruirovanie v Elektronnoi Apparature %D 2012 %I Politehperiodika %X The dependence of the charge collection efficiency n in gamma-ray detectors based on CdZnTe on the impurity composition of the material has been investigated. Plane-parallel, cylindrical and spherical electrodes have been considered. A comparative analysis of n for detectors with electrodes of different shape has been carried out and the optimum composition of the material CdxZn1¨CxTe placed in the electrode gap has been determined. %K CdZnTe %K charge collection %K detectors %K gamma radiation %K simulation %U http://www.tkea.com.ua/tkea/2012/4_2012/pdf/10.zip
