  • Generation of highly N-type, defect passivated transition metal oxides using plasma fluorine insertion
    Patent number: 9312342
    Abstract: A new composition of matter is disclosed wherein oxygen vacancies in a semiconducting transition metal oxide such as titanium dioxide are filled with a halogen such as Fluorine, whereby the conductivity of the composition is greatly enhanced, while at the same time the chemical stability of the composition is greatly improved. Stoichiometric titanium dioxide having less than 3 % oxygen vacancies is subject to fluorine insertion such that oxygen vacancies are filled, limited amounts of fluorine replace additional oxygen atoms and fluorine interstitially inserts into the body of the TiO2 composition.
    Type: Grant
    Filed: December 16, 2011
    Date of Patent: April 12, 2016
    Assignee: The Regents of the University of California
    Inventors: L. Robert Baker, Hyungtak Seo, Antoine Hervier, Gabor A. Somorjai
