Electrons in graphene behave like light, only better

A team led by Cory Dean, assistant professor of physics at Columbia University, Avik Ghosh, professor of electrical and computer engineering at the University of Virginia, and James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, has directly observed—for the first time—negative refraction for electrons passing across a boundary between two regions in a conducting material.
