Technique paves way for 2d #electronics. #graphene #nanotechnology

The Rice University team began by merging graphene and hexagonal boron nitride (h-BN) into sheets and building them into a variety of patterns at nanoscale dimensions. They were then able to lay down different patterns, including their university logo (pictured), through a lithographic process. The interface between the elements was said to show a 'razor sharp' transition from graphene to h-BN along a subnanometre line. "This is not a simple quilt," said Rice researcher Jun Lou. "It's very precisely engineered. We can control the domain sizes and the domain shapes, both of which are necessary to make electronic devices." While there's much work ahead to characterise the atomic bonds where graphene and h-BN domains meet, the researchers are confident that their electrical measurements prove the components' qualities remain intact. "Even by doing all kinds of growth, then et...
