Effect of Internal Bias Field on 180° Domain Switching in Deuterated Glycine Phosphite

Abstract

The switching process in deuterated glycine phosphite crystal (DGPI) has been investigated by microscopic observation of domain structure using nematic liquid crystal (NLC) decoration technique and by switching current registration in high electric fields. The stabilization mechanism of 180° domains appears to have a correlation to a defect—induced internal bias field in the crystal.
