About Feng Wang's Work
Graphene, a one-atom thick sheet of carbon, is a new quantum material where electrons do not move like normal particles with mass, but behave like the massless relativistic photons that make up light. Quantum electronic behavior in graphene can be controlled through electrical gating and interlayer coupling, thus offering tremendous opportunities for new science and technology. As a Packard fellow, I will study the novel relativistic behavior of Dirac fermions in graphene using tabletop measurements. Such condensed matter based experiments provide a high degree of flexibility compared to particle accelerator experiments. I will additionally investigate phonon lasing in graphene based on our new ability to tune the coupling between electrical and vibrational excitations.
