Radiation Effects in Dielectric Materials.
Abstract
A nonlinearity observed in the radiation-induced conductivity versus dose rate plot for a Czochralski sapphire sample is interpreted in terms of a trapping level which is filled early in the pulse at high dose rates but is never completely filled at the low dose rates, thus causing an apparent superlinear dependence of the radiation-induced conductivity. A sample of stoichiometric (MgO . Al2O3) single crystal spinel shows strong trapping at room temperature and a long delayed conductivity component with time constant of approximately 2.3 msec. It is speculated that this trap may be the V1 center, a Mg(+) vacancy observed at elevated temperatures in single crystal MgO. (Author)
