Abstract
We study the transmission probability of Dirac fermions in graphene scattered by a triangular double barrier potential in the presence of an external magnetic field. Our system is made of two triangular potential barrier regions separated by a well region characterized by an energy gap Gp. Solving our Dirac-like equation and matching the solutions at the boundaries, we express our transmission and reflection coefficients in terms of the transfer matrix. We show in particular that the transmission exhibits oscillation resonances that are the manifestation of the Klein tunneling effect.
