Thin films of various thicknesses in the MIM structure have been prepared from the powder of SnO,/Sb,O, mixed sample by the thermal evaporation technique in a vacuum of Torr. Dielectric properties of Sn02/Sb,03 mixed thin films have been studied with temperature starting from LNT to RT and above RT and frequency ranging from 100Hz to 16kHz. The activation energy for the migration of charge carriers in SnO,/Sb,O, mixed thin films has been calculated and it is found to be 0.23 eV. The results thus obtained on dielectric properties of SnO,/Sb,O, mixed thin films are presented and discussed. WILLIAMS G. HYNES, RICHARD H. BUBE: J. Appl.
