Query: Double Barriers and Magnetic Field in Bilayer Graphene   We study the transmission probability in an AB-stacked bilayer graphene of
Dirac fermions scattered by a double barrier structure in the presence of a
magnetic field. We take into account the full four bands of the energy spectrum
and use the boundary conditions to determine the transmission probability. Our
numerical results show that for energies higher than the interlayer coupling,
four ways for transmission probabilities are possible while for energies less
than the height of the barrier, Dirac fermions exhibits transmission resonances
and only one transmission channel is available. We show that, for AB-stacked
bilayer graphene, there is no Klein tunneling at normal incident. We find that
the transmission displays sharp peaks inside the transmission gap around the
Dirac point within the barrier regions while they are absent around the Dirac
point in the well region. The effect of the magnetic field, interlayer
electrostatic potential and various barrier geometry parameters on the
transmission probabilities are also discussed.
