Abstract
Molybdenum trioxide films were grown by an electron beam evaporation t echnique onto Coming glass substrates maintained at temperatures in th e range 303-573 K. The films were characterized by studying their stru cture and optical properties. The d.c. conductivity studies revealed t hat electron hopping and thermally activated conduction processes were operated in the temperature range 160-400 K. The frequency and temper ature dependences of the capacitance and the dielectric loss were syst ematically studied and the activation energy is found to be about 0.3 eV.
