Super-Klein tunneling of Dirac fermions through electrostatic gratings in graphene
Alonso Contreras-Astorga, Francisco Correa, Vít Jakubský
Abstract
We use the Wick-rotated time-dependent supersymmetry to construct models of two-dimensional Dirac fermions in the presence of an electrostatic grating. We show that there appears omnidirectional perfect transmission through the grating at specific energy. Additionally to being transparent for incoming fermions, the grating hosts strongly localized states.
