Query: Transmission via Triangular Double Barrier and Magnetic Fields in
  Graphene   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 made of two triangular potential barrier regions
separated by a well region characterized by an energy gap $G_p$. Solving our
Dirac-like equation and matching the solutions at the boundaries we express our
transmission and reflection coefficients in terms of transfer matrix. We show
in particular that the transmission exhibits oscillation resonances that are
manifestation of the Klein tunneling effect.
