Controlling Spin-Polarization in Graphene by Cloaking Magnetic and Spin-Orbit Scatterers
Diego Oliver, Tatiana G. Rappoport
We consider spin-dependent scatterers with large scattering cross-sections in graphene -a Zeeman-like and an intrinsic spin-orbit coupling impurity- and show that a gated ring arou…

Cloaking Resonant Scatterers and Tuning Electron Flow in Graphene
Diego Oliver, Jose H. Garcia, Tatiana G. Rappoport +2
We consider resonant scatterers with large scattering cross-sections in graphene that are produced by a gated disk or a vacancy, and show that a gated ring can be engineered to pro…
