摘要
Peculiarities of morphology and electric properties of X-ray and gamma-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/cm(2) has been carried out in order to modify and improve their structure and phase state.
