, Home Introduction Graphene Investing New technique creates thin , flexible and transparent graphene and boron-nitride films Tweet Electronics Flexible Graphene applications Technical Research Transparency Researchers from Cornell University have managed to pattern single atom films of graphene and boron nitride , an insulator , without the use of a silicon substrate . They are using a technique they call patterned regrowth , and they say this could lead towards substrate-free , atomically thin circuits . These will be so thin that they could be transparent and flexible , and yet have great electrical . performance Patterned regrowth uses the same basic photolithography technology used in silicon wafer processing , and it allows graphene and boron nitride to grow in perfectly flat ,
