摘要：

We demonstrate that illuminating a photoconducting strontium barium niobate crystal with a low intensity optical standing wave generates space charge fields which induce ferroelectric domain gratings. We study the formation and decay kinetics of these domain gratings using a short exposure technique and present a thermodynamic model of the fixing mechanism.
