  • Publication number: 20220384197
    Abstract: The current disclosure relates to deposition of a transition metal chalcogenide barrier layer. The method of depositing a transition metal chalcogenide barrier layer comprises providing a substrate having an opening into a reaction chamber, providing a transition metal precursor in the reaction chamber in vapor phase and providing an reactive chalcogen species in the reaction chamber. The method may be a plasma-enhanced atomic layer deposition method. The disclosure further relates to an interconnect comprising a transition metal chalcogenide barrier layer.

  • Patent number: 9064842
    Abstract: A semiconductor device includes a substrate, first plural contacts formed in the substrate, a graphene layer formed on the substrate and on the first plural contacts and second plural contacts formed on the graphene layer such that the graphene layer is formed between the first plural contacts and the second plural contacts.
    Type: Grant

  • Patent number: 8853034
    Abstract: Techniques for increasing conductivity of graphene films by chemical doping are provided. In one aspect, a method for increasing conductivity of a graphene film includes the following steps. The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided.

  • Publication number: 20130025662
    Abstract: Techniques for reducing the resistivity of carbon nanotube and graphene materials are provided. In one aspect, a method of producing a doped carbon film having reduced resistivity is provided. The method includes the following steps. A carbon material selected from the group consisting of: a nanotube, graphene, fullerene and pentacene is provided. The carbon material and a dopant solution comprising an oxidized form of ruthenium bipyridyl are contacted, wherein the contacting is carried out under conditions sufficient to produce the doped carbon film having reduced resistivity.
