Abstract
A method for improving CdZnTe-based gamma-ray detectors is presented. A CdZnTe detector/crystal is exposed to acoustic waves. After exposure to acoustic waves, the CdZnTe gamma-detector gains higher resistivity and exhibits better spectral resolution and greater sensitivity. Further, when a batch of detectors is made according to the method of the present invention, the properties of the crystals are more homogenous, allowing for cheaper and more standardized detectors.
