This work investigates how crystallographic orientation influences charge transport and photoresponse in planar CdTe X-ray detectors. By correlating structural orientation with carrier collection efficiency and transient behavior, the study reveals anisotropic transport and trapping mechanisms that directly impact detector sensitivity and signal stability. These findings establish orientation engineering as a key parameter for optimizing CdTe-based radiation detection devices.
