ASSESSMENT OF DISLOCATION INTERACTION PROCESSES WITH GRAIN BOUNDARIES BY NONLINEAR OPTICAL SPECTROSCOPY
Abstract
The presence of grain boundaries has a crucial influence on dislocation behaviors and oxygen migration dynamics and therefore drastically change the electronic and mechanical properties of dielectric and ferroelectric materials. We propose to investigate the polymorphic nanodomain phenomena with grain boundaries, including the structural phase separation, phase segregation, strain relaxation with oxygen vacancy migrations, and ionic defect dynamics at interfacial and bulk regions in prototypical dielectrics and ferroelectrics by nonlinear optical spectroscopy.
