The effect of laser treatment on the morphology of graphene/CdTe X-ray and γ-ray detectors

Peculiarities of morphology and electric properties of X-ray and γ-ray detectors developed by graphene deposition onto commercially available (111) oriented CdTe:Cl wafers has been investigated. Laser treatment of graphene contact using millisecond YAG-laser with an energy density of 0.1–4.5 J/cm2 has been carried out in order to modify and improve their structure and phase state.
