Snake states and Klein tunneling in a graphene Hall bar with a pn-junction
Michael Barbiër, György Papp, François M. Peeters
The Hall (RH) and bend (RB) resistance of a graphene Hall bar structure containing a pn-junction are calculated when in the ballistic regime. The simulations are done using the bil…
Single-layer and bilayer graphene superlattices: collimation, additional Dirac points and Dirac lines
M. Barbier, P. Vasilopoulos, F. M. Peeters
We review the energy spectrum and transport properties of several types of one- dimensional superlattices (SLs) on single-layer and bilayer graphene. In single-layer graphene, for…
Kronig-Penney model on bilayer graphene: spectrum and transmission periodic in the strength of the barriers
M. Barbier, P. Vasilopoulos, F. M. Peeters
We show that the transmission through single and double δ-function potential barriers of strength P in bilayer graphene is periodic in P with period π. For a certain range of P val…
Bilayer graphene with single and multiple electrostatic barriers: band structure and transmission
M. Barbier, P. Vasilopoulos, F. M. Peeters +1
We evaluate the electronic transmission and conductance in bilayer graphene through a finite number of potential barriers. Further, we evaluate the dispersion relation in a bilayer…
Dirac and Klein-Gordon particles in one-dimensional periodic potentials
M. Barbier, F. M. Peeters, P. Vasilopoulos +1
We evaluate the dispersion relation for massless fermions, described by the Dirac equation, and for zero-spin bosons, described by the Klein-Gordon equation, moving in two dimensio…
Extra Dirac points in the energy spectrum for superlattices on single-layer graphene
M. Barbier, P. Vasilopoulos, F. M. Peeters
We investigate the emergence of extra Dirac points in the electronic structure of a periodically spaced barrier system, i.e., a superlattice, on single-layer graphene, using a Dira…
