Periodically Gated Bilayer Graphene as an Electronic Metamaterial
arXiv:2001.03081 · doi:10.1103/PhysRevApplied.13.034034
Abstract
We study ballistic transport in periodically gated bilayer graphene as a candidate for a 2D electronic metamaterial. Our calculations use the equilibrium Green function formalism and take into account quantum corrections to charge density changes induced by a periodically modulated top gate voltage. Our results reveal an intriguing interference-like pattern, similar to that of a Fabry-Perot interferometer, in the resistance map as a function of the voltage applied to the extended bottom gate and applied to the periodic top gate.
