Mie scattering analog in graphene: Lensing, particle confinement, and depletion of Klein tunneling

Guided by the analogy to Mie scattering of light on small particles, we show that the propagation of a Dirac-electron wave in graphene can be manipulated by a circular gated region acting as a quantum dot. Large dots enable electron lensing, while for smaller dots resonant scattering entails electro...
