Velocity-modulation control of electron-wave propagation in graphene
arXiv:0912.2608 · doi:10.1103/PhysRevB.81.073407
Abstract
Wave propagation control by spatial modulation of velocity has a long history in optics and acoustics. We address velocity-modulation control of electron wave propagation in graphene and other two-dimensional Dirac-electron systems, pointing out a key distinction of the Dirac-wave case. We also propose a strategy for pattern transfer from a remote metallic layer that is based on many-body velocity renormalization.
