Rice technique points toward 2-D devices
Date:1/27/2013

here graphene and h-BN domains meet and to analyze potential defects along the boundaries, Liu's electrical measurements proved the components' qualities remain intact.

"One important thing Zheng showed is that even by doing all kinds of growth, then etching, then regrowth, the intrinsic properties of these two materials are not affected," Lou said. "Insulators stay insulators; they're not doped by the carbon. And the graphene still looks very good. That's important, because we want to be sure what we're growing is exactly what we want."

Liu said the next step is to place a third element, a semiconductor, into the 2-D fabric. "We're trying very hard to integrate this into the platform," he said. "If we can do that, we can build truly integrated in-plane devices." That would give new options to manufacturers toying with the idea of flexible electronics, he said.

"The contribution of this paper is to demonstrate the general process," Lou added. "It's robust, it's repeatable and it creates materials with very nice properties and with dimensions that are at the limit of what is possible."
