Description
Summary:The results of a study of the electrophysical characteristics of ITO films obtained by magnetron sputtering are presented. It is shown that a significant increase in the electrical conductivity of ITO films is facilitated by high-temperature annealing due to two processes. First, the high-temperature treatment of ITO films after their synthesis promotes the formation of a crystal structure, which leads to an increase in the mobility of charge carriers. Second, as a result of high-temperature annealing, the impurity in ITO films becomes completely electrically active, which leads to an increase in the concentration of conduction electrons and a change of the semiconductor mechanism of electrical conductivity to the metallic one.
