Spectroscopy of the Dirac oscillator perturbed by a surface delta potential
J. Munárriz, F. Domínguez-Adame, R. P. A. Lima
We study theoretically the level shift of the Dirac oscillator perturbed by any sharply peaked potential approaching a surface delta potential. A Green function method is used to o…
Strong spin-dependent negative differential resistance in composite graphene superlattices
J. Munárriz, C. Gaul, A. V. Malyshev +3
We find clear signatures of spin-dependent negative differential resistance in compound systems comprising a graphene nanoribbon and a set of ferromagnetic insulator strips deposit…
Graphene nanoring as a tunable source of polarized electrons
Javier Munárriz, Francisco Domínguez-Adame, Pedro A. Orellana +1
We propose a novel spin filter based on a graphene nanoring fabricated above a ferromagnetic strip. The exchange interaction between the magnetic moments of the ions in the ferroma…
