Paper Abstract

The effect of laser irradiation on amorphous films of anodic vanadium oxide was studied using a YAG:Nd3+ laser at wavelength 1.06 micrometers . Irradiation was found to lower the electrical conductivity of the oxide films and modify significantly the parameters of electroforming and switching in metal/oxide/metal sandwich structures. The threshold energy for laser modification was measured to be approximately 0.3 mJ/cm2. It is shown that the changes of the electrical properties are associated with structural (crystallization) and chemical (in particular, the reduction V2O5 yields VO2) transformations and that non- thermal photo-stimulated effects play an important role in the laser modification of the vanadium oxide thin films.
