  • Hole doping of graphene
    Patent number: 9269773
    Abstract: An article includes a layer of graphene having a first work function; and a metal oxide film disposed on the layer of graphene, the metal oxide film having a second work function greater than the first work function. Electrons are transferred from the layer of graphene to the metal oxide film, forming a hole accumulation layer in the layer of graphene.
    Type: Grant
    Filed: May 5, 2011
    Date of Patent: February 23, 2016
    Assignee: National University of Singapore
    Inventors: Wei Chen, Zhenyu Chen, Thye Shen Andrew Wee, Lanfei Xie, Xiao Wang, Jiatao Sun, Ariando
