Yes, we’ve been marching on this road to graphene-based superconductive electronics for a long, long time. But in the space of one week, we’ve now seen two significant advancements pop up that rekindle our hope for an ultrafast tomorrow. Hot on the heels of IBM’s recent bandgap achievement comes Penn State University with a 100mm wafer of pure graphene gorgeousness. Built using silicon sublimation — a process of essentially evaporating the silicon away from the carbon layer — these are the biggest graphene wafers yet, and field effect transistors are being built atop them now to start performance testing early this year. Naturally, nobody’s sitting on this laurel just yet, with further plans afoot to expand beyond 200mm wafers in order to integrate fully into the semiconductor industry, whose current standard wafer size is around 300mm in diameter. On we go then.

Penn State busts out 100mm graphene wafers, halcyonic dream inches closer to reality originally appeared on Engadget on Wed, 03 Feb 2010 10:17:00 EST. Please see our terms for use of feeds.
