Influence of optical concentration on the properties of Indium oxide thin films — •Nevin Kalkan — Istanbul Univ., Science Faculty, Physics Dept. Vezneciler/ Istanbul - TURKEY

Current - voltage characteristics of Indium-embedded Indium oxide thin films (550-850 Å) with Ag electrodes approximately 1000 Å in thickness, prepared by reactive evaporation of pure indium in partial air pressure were studied. The electrical and optical properties of these films have been investigated as a function of optical concentration. It is seen that the I-V characteristics of all the samples are non-ohmic independent of optical concentration. The conductivity of the films was also seen to increase with the optical concentration. Furthermore, for possible conduction mechanism were proposed.

Keywords: Conduction mechanism, Poole-Frenkel mechanism, chalcogenide
