Abstract:
A method of patterning a metal oxide surface at ambient pressure, comprising steps of:a) providing a substrate coated with a metal oxide selected from the group consisting of indium zinc oxide and indium tin oxide; b) providing a stamp having a substantially continuous surface with at least one indentation; c) coating said stamp surface with a molecular species comprising an alkyl group which is fully or partially fluorinated terminating with a phosphoric acid group and has the formula (CF3(CF2)m(CH2)n), where n+m=0-20 which molecular species is capable of reacting with said metal oxide surface to form a bond between said phosphoric acid group and said metal oxide surface; d) positioning said coated stamp on the surface of said metal oxide such that said phosphoric acid group contacts and reacts with at least a portion of said metal oxide surface to form a bond therebetween; e) removing said stamp from the surface of said metal oxide to obtain a self-assembled monolayer comprising the reaction product of said phosphoric acid group of said molecular species and said metal oxide.
