Title: Hole-electron electrical coupling in photorefractive materials
Author: de Oliveira, I
Montenegro, R
Frejlich, J
Abstract: We describe an improved mathematical model for photorefractive materials exhibiting hole-electron competition where the constants accounting for electrical coupling between holes and electrons are independently adjusted for each one of them. Experimental results from photorefractive titanosillenite crystals with hole-electron competition, and particularly from a vanadium doped sample, are shown to be better described by this modified model than by the classical one already reported in the literature.
