Some aspects of radiation resistance of wide-gap metal oxides

Wide-gap oxides drastically differ in radiation resistance against nonimpact mechanisms of defect creation depending on the ratio between the values of the energy gap Eg and the formation energy of a pair of Frenkel defects (FD) EFD. Materials with Eg>EFD are radiation-sensitive even at a low excitation density, while the efficiency of FD creation in the materials with Eg
