The main preoccupation with graphene research has been trying to impart a band gap to the wonder material. Researchers at the University of Wisconsin-Milwaukee were able to get graphene to behave like a semiconductor earlier this year by making a new variety of graphene dubbed “graphene monoxide”. But now researchers at National Institute of Standards and Technology (NIST) and the University of Maryland discovered they could do it by just treating graphene like a drumhead . The research was published in the journal Science under the title “Electromechanical Properties of Graphene Drumheads ” and is available with a subscription. Initially the aim of the NIST and University of Maryland team was to see if they could just slow electrons down with the use of a substrate. So they suspended a layer of graphene over a substrate of silicon dioxide that contained shallow holes. Whe...
