Abstract

The effect of a ZnSe layer on the thermochromic properties of MoO 3 thin films was investigated. ZnSe/MoO3 and MoO 3 thin films were deposited by thermal evaporation in vacuum of MoO3 and ZnSe powders. Photoacoustic spectra of the films indicated that the thermochromic response for the ZnSe/MoO3 bilayer system was more accentuated, with respect to the MoO3 sample, for temperature treatments above 150 C. This result is explained in terms of the injection of electrons from the II-VI semiconductor to the oxide film.
