Abstract
Undoped CdSe single crystals were investigated by current- voltage measurement and low temperature photoluminescence. Crystal quality and surface morphology were also studied by optical microscopy and scanning electron microscopy. Together with gamma spectroscopy, the results show that the CdSe crystals have high resistivities in the 1010 (Omega) (DOT)cm range. This indicates their usefulness for room temperature nuclear radiation detection. Small active volume CdSe detector were fabricated and their performance is presented. A comparison of fundamental material properties between CdSe and CdZnTe detectors is also given.
