  • Patent number: 10319825
    Abstract: A TMD system in which the first layered material is made of heterobilayers or multilayers with semiconducting direct band gaps is provided. The first layered material may be made of multiple layers of different TMD with different stackings, exhibiting smaller direct and indirect band gaps smaller than monolayer systems of TMD.

  • Patent number: 9284193
    Abstract: We report a method of preparation of highly elastic graphene oxide films, and their transformation into graphene oxide fibers and electrically conductive graphene fibers by spinning. Methods typically include: 1) oxidation of graphite to graphene oxide, 2) preparation of graphene oxide slurry with high solid contents and residues of sulfuric acid impurities. 3) preparation of large area films by bar-coating or dropcasting the graphene oxide dispersion and drying at low temperature. 4) spinning the graphene oxide film into a fiber, and 5) thermal or chemical reduction of the graphene oxide fiber into an electrically conductive graphene fiber. The resulting films and fiber have excellent mechanical properties, improved morphology as compared with current graphene oxide fibers, high electrical conductivity upon thermal reduction, and improved field emission properties.
