Abstract
Abstract A light transmissive, electrically conductive oxide comprising tin and a Group II element is doped with a Group III element and with one or more of hydrogen or fluorine. The oxide may be deposited by sputtering at a temperature in the range from 25 DEG to 350 DEG C., or by chemical vapor deposition at temperatures in the range from 80 DEG to 400 DEG C.
