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

► Reproducibly grown large-volume CdMgTe single crystals. ► High resistivity and good mobility-lifetime was found of our grown CdMgTe crystals. ► Reasonably good spectral response was recorded from CdMgTe planar detectors. ► Highly promising alternative of CdZnTe crystals.
