Development of Cadmium Magnesium Telluride (Cd1-xMgxTe) for room temperature X- and gamma-ray detectors

Original language description

Cadmium Magnesium Telluride (Cd1-xMgxTe/CMgT) offers several pronounced potential advantages over the well-studied CdZnTe and CdMnTe, possibly making it a good alternative for room-temperature X- and gamma-ray detectors. It possesses high crystallinity due to the near-similar lattice structure of CdTe (6.48 angstrom) and MgTe (6.42 angstrom). Its displays good homogeneity as the Mg segregation coefficient in CdTe is nearly 1. Furthermore, inhomogeneities in the crystal due to alloying effects can be minimized, because the optimal energy band-gap can be achieved using less Mg in CdMgTe compared to Zn and Mn needed in CdZnTe and CdMnTe. We recently grew an undoped- and a doped-ingot of CdMgTe, characterized its material properties, and tested its detection performance. We obtained some exciting results that demonstrated some of its potential advantages over the other materials. The band-gap was measured as 1.61 eV at room temperature and 1.73 eV at 4 K. The yield was predominantly single
