Abstract
To understand the dynamics of photoinduced volume expansion (PVE) in amorph ous chalcogenides, in situ PVE (time evolution of thickness changes during illumination) measurements have been performed. Two distinct behaviors, tra nsient and metastable PVE, have been observed. A strong correlation between the changes in thickness and photocurrent is reported. (C) 1999 American I nstitute of Physics.
