Abstract

The results of studies of electrical and gas-sensitive characteristics of thin films Ga2O3:Si on exposure to oxygen in the range from 0 to 100 vol. % and operating temperatures from 25 to 700 °C were presented. Samples were obtained by HF magnetron sputtering. The possibility of developing low-temperature oxygen sensors was shown. A model of oxygen interaction with Ga2O3:Si films was proposed. The mechanism of Si influence on gas-sensitive properties of thin films of gallium oxide was proposed.
