Patent number: 11172579Abstract: A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.Type: GrantFiled: December 5, 2019Date of Patent: November 9, 2021Assignee: NCC NANO, LLCInventors: Dave S. Pope, Kurt A. Schroder, Ian M. Rawson
