New Technique Could Mean Super Thin, Strong Graphene-Based Circuits, Cornell University Study

Integrated circuits, which are in everything from coffeemakers to computers and are patterned from perfectly crystalline silicon, are quite thin — but Cornell researchers think they can push thin-film boundaries to the single-atom level. Their materials of choice are graphene, single atom-thick sheets of repeating carbon atoms, and hexagonal boron nitride, similarly thin sheets of repeating boron and nitrogen atoms. Researchers led by Jiwoong Park, assistant professor of chemistry and chemical biology, have invented a way to pattern single atom films of graphene and boron nitride, an insulator, without the use of a silicon substrate. The work is detailed in an article in the journal Nature, published online Aug. 30.
