Abstract

Cd_1-xMn_xTe is a promising material that has been introduced as a potential successor for the popular Cd_1-xZn_xTe material in the field of room-temperature gamma-ray detection. In this work, we demonstrate a planar array on a 5 mm thick Cd_1-xMn_xTe detector with spectroscopy performance similar to that of industrial Cd_1-xZn_xTe devices of the same thickness. The uniformity of Cd_1-xMn_xTe was theoretically predicted and experimentally demonstrated to be superior to that of Cd_1-xZn_xTe due to a better solubility of manganese. The main challenge until now was to exhibit large area, thick Cd_1-xMn_xTe arrays with satisfactory spectroscopy performance. In this Letter, static as well as spectroscopic properties of thick Cd_1-xMn_xTe devices are compared to those of conventional Cd_1-xZn_xTe detectors, grown by the same technology (horizontal Bridgman).
