Abstract
We demonstrate that illuminating a photoconducting strontium barium ni obate crystal with a low intensity optical standing wave generates spa ce charge fields which induce ferroelectric domain gratings. We study the formation and decay kinetics of these domain gratings using a shor t exposure technique and present a thermodynamic model of the fixing m echanism.
