Columbia University physics professor Philip Kim, who is a coauthor of the new paper, says that chemical vapor deposition is one of the cheapest ways to make quality graphene on a large scale and should be compatible with existing semiconductor fabrication technologies. Right now, the researchers can make four-inch pieces, but Hong says that they could easily scale up the process. “The conductivity is sufficient for some entry-level applications in small LCD displays and touch-panel displays,” says Yang Yang, a materials-science and engineering professor at the University of California, Los Angeles.
