Ion Beam Induced Charge Studies of CdZnTe Grown by Modified Vertical Bridgman Method

Ion beam induced charge (IBIC) and time resolved digital IBIC techniques have been used to map the electronic properties of CdZnTe manufactured by Yinnel Tech Inc. The 2 MeV proton scanning microbeam at the University of Surrey Ion Beam Centre was used to map the charge transport properties of both holes and electrons at room temperature. The electron response of the detector showed good uniformity whereas the hole response showed significant variations across the bulk.
