Spectroscopy of snake states using a graphene Hall bar
S. P. Milovanovic, M. Ramezani Masir, F. M. Peeters
An approach to observe snake states in a graphene Hall bar containing a pn-junction is proposed. The magnetic field dependence of the bend resistance in a ballistic graphene Hall b…
Bilayer graphene Hall bar with a pn-junction
S. P. Milovanovic, M. Ramezani Masir, F. M. Peeters
We investigate the magnetic field dependence of the Hall and the bend resistances for a ballistic Hall bar structure containing a pn-junction sculptured from a bilayer of graphene.…
Graphene Hall bar with an asymmetric pn-junction
S. P. Milovanovic, M. Ramezani Masir, F. M. Peeters
We investigated the magnetic field dependence of the Hall and the bend resistances in the ballistic regime for a single layer graphene Hall bar structure containing a pn-junction.…
Electronic states in a graphene flake strained by a Gaussian bump
D. Moldovan, M. Ramezani Masir, F. M. Peeters
The effect of strain in graphene is usually modeled by a pseudo-magnetic vector potential which is, however, derived in the limit of small strain. In realistic cases deviations are…
Pseudo magnetic field in strained graphene: revisited
M. Ramezani Masir, D. Moldovan, F. M. Peeters
We revisit the theory of the pseudo magnetic field as induced by strain in graphene using the tight-binding approach. A systematic expansion of the hopping parameter and the deform…
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…
