Abstract
We report deep level characterization on CdZnTe nuclear detectors grown by the high pressure Bridgman method. Three CdZnTe samples taken from the top, middle and tail of the same ingot were investigated using photo-induced cu rrent transient spectroscopy and thermoelectric-effect spectroscopy. Three major traps are detected and their influence on the nuclear detection prope rties are discussed. (C), 1999 Elsevier Science B.V. All rights reserved.
