Abstract:
1. A method for preparing a doped, p-type tin oxide layer on a substrate, the method comprising the step of: depositing the tin oxide layer on the substrate by atmospheric pressure chemical vapor deposition using a tin oxide precursor in a carrier gas; in which: the tin oxide precursor comprises a vaporizable tin compound; the tin oxide precursor comprises less than about 0.01 weight percent total d and f transition metals; the carrier gas comprises nitrogen, nitrous oxide, and oxygen; the flow rates are nitrogen, 2-20 L/min; nitrous oxide, 1-10 L/min; and oxygen, 20-160 cm the carrier gas additionally comprises a dopant precursor; the dopant precursor is an Al, Ga, or In compound; and the resulting tin oxide is doped, p-type tin oxide.
