The determination of the carrier mobility in transparent ferroelectric ceramics

Condensed matter physics

The surface potential decay in transparent ferroelectric ceramics PLZT-9 determined by charge relaxation processes in ceramics has been studied. The experimental results were analyzed on the basis of dispersive transport model that proposed repeated trapping of charge carriers into deep traps with their consequent thermal releasing and moving through ceramics bulk. The time-dependence of carrier mobility at constant temperature was calculated.
