Abstract

CoMnNiO thin film deposited by rf sputtering is a combination of various amorphous metal oxides. Its DC conductivity changes smoothly with temperature from 173 to 373 K. The relation of AC conductivity with frequency can be written as (sigma) ((omega))∝(omega)^s. Its thermopower is positive and its mobility at 330 K is about 1.25 cm²V^-1S^-1, which is thermally activated. It can be inferred that small polaron conduction is included in the conduction of this amorphous thin film.
