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.
