FABRICATION OF SINGLE-CRYSTALLINE GRAPHENE ARRAYS

摘要

The present disclosure demonstrates the synthesis of ordered arrays of GSC's by re- growth from pre-patterned seed crystals, offering an approach for scalable fabrication of single crystal graphene devices while avoiding domain boundaries. Each graphene island is a single crystal and every graphene island is of similar size. The size of graphene island arrays can be as small as less than 1 mm² or as large as several m². The distance between each GSC island is also adjustable from several micrometers to millimeters. All of the graphene islands are addressable for devices and electrical circuit fabrication.
