Modification of graphene photodetector by TiO.sub.2 prepared by oxygen plasma

Single-layer graphene has been proved to be an ideal material for broadband high-speed photodetector. However, the pure graphene photodetector photoresponsivity is limited to tens of mA/W by the low optical absorption and short exciton life of graphene. When higher responsivity is needed, the graphe...
