Whisker Growth induced by Ag photodoping in glassy Ge<i>x</i>Se1−<i>x</i> films

Abstract

The growth and disappearance of crystalline Se whiskers in glassy GexSe1−x films ( with x=0.1 and (1)/(3) ) during the process of Ag photodoping have been studied by electron microscopy. The longitudinal growth direction of the whiskers is found to be parallel to the c axis of the Se hexagonal lattice.
