Barrier to Faster Graphene Devices Identified and Suppressed, Vanderbilt University Study


3/14/2012 7:31:33 AM

These days graphene is the rock star of materials science, but it has an Achilles heel: It is exceptionally sensitive to its electrical environment. This single-atom-thick honeycomb of carbon atoms is lighter than aluminum, stronger than steel and conducts heat and electricity better than copper. As a result, scientists around the world are trying to turn it into better computer displays, solar panels, touch screens, integrated circuits and biomedical sensors, among other possible applications. However, it has proven extremely difficult to reliably create graphene-based devices that live up to its electrical potential when operating at room temperature and pressure.
