Resonant valley filtering of massive Dirac electrons
D. Moldovan, M. Ramezani Masir, L. Covaci +1
Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom: sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a car…
Scattering of a Dirac electron on a mass barrier
A. Matulis, M. Ramezani Masir, F. M. Peeters
The interaction of a wave packet (and in particular the wave front) with a mass barrier is investigated in one dimension. We discuss the main features of the wave packet that are i…
Wavevector filtering through single-layer and bilayer graphene with magnetic barrier structures
M. Ramezani Masir, P. Vasilopoulos, F. M. Peeters
We show that the angular range of the transmission through magnetic barrier structures can be efficiently controlled in single-layer and bilayer graphenes and this renders the stru…
Quasi-bound states of Schrodinger and Dirac electrons in magnetic quantum dot
M. Ramezani Masir, A. Matulis, F. M. Peeters
The properties of a two-dimensional electron are investigated in the presence of a circular step magnetic field profile. Both electrons with parabolic dispersion as well as Dirac e…
