FAILURE MECHANISMS IN FERROELECTRIC AND NONLINEAR DIELECTRICS

Abstract

The electrical conductivity of SrTiO3 was measured by dc and microwave techniques. Pure, doped, and oxygen deficient material was studied and the temperature dependence of the conductivity was observed. Activation energies in the pure materials and mobilities in the oxygen deficient materials were measured. Preliminary studies of the breakdown voltages in pure SrTiO3 showed bulk breakdown strengths of 10 to the 6th power v/cm. The temperature dependence of the electrostrictive constant g sub 31 was studied in the paraelectric temperature range for pure single crystal SrTiO3. Annealing procedures were developed for the strain-relief of flame fusion grown SrTiO3 boules. (Author)
