摘要: A mixture of single-walled carbon nanotubes (“SWNTs”) is separated into fractions of enriched chirality by preparing an aqueous suspension of a mixture of SWNTs and a surfactant, injecting a portion of the suspension on a column of separation medium having a density gradient, and centrifuging the column. In some embodiments, salt is added prior to centrifugation. In other embodiments, the centrifugation is performed at a temperature below room temperature. Fractions separate as colored bands in the column. The diameter of the separated SWNTs decreases with increasing density along the gradient of the column. The colored bands can be withdrawn separately from the column.

摘要: A method for optimizing graphene synthesis is provided. The method includes providing a substrate having a plurality of site isolated regions defined thereon and depositing a metal layer within each region of the plurality of site isolated regions. The metal layer is combinatorially deposited among the plurality of site isolated regions. The method includes synthesizing a graphene layer over each metal layer within each region of the plurality of site isolated regions and evaluating grain boundary profiles in the synthesized graphene layer over each metal layer within each region of the plurality of site isolated regions.

摘要: A method for depositing graphene is provided. The method includes depositing a layer of non-conducting amorphous carbon over a surface of a substrate and depositing a transition metal in a pattern over the amorphous carbon. The substrate is annealed at a temperature below 500° C., where the annealing converts the non-conducting amorphous carbon disposed under the transition metal to conducting amorphous carbon. A portion of the pattern of the transition metal is removed from the surface of the substrate to expose the conducting amorphous carbon.
