We studied the impact of boundary walls and inclusions to the charge collection efficiency (CCE) of cadmium telluride (CdTe) pad detectors. By using ion beam-induced charge (IBIC) analysis, we were able to locate and classify various defects. We used

Aluminium oxide (Al2O3) has been proposed as an alternative to thermal silicon dioxide (SiO2) as field insulator and surface passivation for silicon detectors, where it could substitute p-stop/p-spray insulation implants between pixels due to its neg

The suitability of two low-temperature dielectric passivation layer processes for the fabrication of Cadmium Telluride (CdTe) X-ray detectors has been investigated. The CdTe crystals with a size of (10 × 10 × 1) mm 3 were coated with sputtered alum

Tellurium defects in CdTe and CdZnTe detectors are known to degrade the detector performance by trapping passing charges. This causes losses in charge collection and ultimately degrades the energy resolution. The amount and size of the defects has pr
