With each new generation of microchips, transistors are being placed closer and closer together. This can only go on so long before there’s no more room to improve, or something revolutionary has to come along to change everything. One of the materials that might be the basis of that revolution is none other than graphene. Researchers at the University of California at Berkeley are hot on the trail of a form of so-called nanoribbon graphene that could increase the density of transistors on a computer chip by as much as 10,000 times.
