We investigate the electronic transport properties of a
bilayer graphene nanoribbon as n-p and n-n junctions subjected to a
perpendicular magnetic field in the presence of on-site or edge
disorder. Our studies stem from the non-equilibrium Green's
function and the Landauer-Büttiker formalism to solve
the tight-binding Hamiltonian of the bilayer graphene nanoribbon connected to leads. We
show that the Hall plateaux remains unchanged in the presence of
disorders in the n-n region. In addition, in the n-p region, disorders
induce the enhancement of the conductance in the presence
of the magnetic field.
