20120241069 | Direct Synthesis of Patterned Graphene by Deposition - A graphene pattern is fabricated by forming a pattern of passivation material on a growth substrate. The pattern of passivation material defines an inverse pattern of exposed surface on the growth substrate. A carbon-containing gas is supplied to the inverse pattern of the exposed surface of the growth substrate, and patterned graphene is formed from the carbon. The passivation material does not facilitate graphene growth, and the inverse pattern of exposed surface of the growth substrate facilitates graphene growth on the exposed surface of the growth substrate. | 09-27-2012 |

20130340533 | STRAIN GAUGE USING TWO-DIMENSIONAL MATERIALS - Strain gauge. The gauge includes a substrate and a thin film of overlapping, two-dimensional flakes deposited on the substrate. Structure responsive to conductance across the film is provided whereby a strain induced change in overlap area between neighboring flakes results in a change in conductance across the film. In a preferred embodiment, the two-dimensional flakes are graphene. | 12-26-2013 |
20140245946 | Synthesis and Transfer of Transition Metal Disulfide Layers on Diverse Surfaces - Aromatic molecules are seeded on a surface of a growth substrate; and a layer (e.g., a monolayer) of a metal dichalcogenide is grown via chemical vapor deposition on the growth substrate surface seeded with aromatic molecules. The seeded aromatic molecules are contacted with a solvent that releases the metal dichalcogenide layer from the growth substrate. The metal dichalcogenide layer can be released with an adhered transfer medium and can be deposited on a target substrate. | 09-04-2014 |
