Dose rate dependence of carrier mobility

The trap-modulated steady-state carrier mobility in insulators depends on the relation between free and trapped carriers. Under irradiation this relation changes due to the radiation-induced shift of the Fermi level. Therefore mobility is a function of dose rate. This function can be calculated when the radiation-induced steady-state conductivity is given as a function of dose rate. If the latter is given by a power law, the former is also given by such a law.
