  The important experimental advances in graphene fabrication and its peculiar
transport properties motivated researchers to utilize graphene as a potential
basis for the next generation of fast and smart electronic devices. In this
article, we investigate the influence of a potential substrate on the transport
properties of a biased AA-stacked n-p-n bilayer graphene junction (AA-BLG).
Using the Dirac Hamiltonian with the transfer matrix approach we obtain the
transmission probabilities and thus the respective conductance. In the presence
of the induced mass-term, the energy spectrum and the intra-cone transmission
drastically change while the inter-cone transmission remains zero. On the other
hand, the bias slightly alters the energy spectrum but it significantly affects
the transport properties due to its ability to switch on the inter-cone
transmission. In addition, we find that Klein tunneling is attenuated in the
presence of the induced mass-term which can improve the carriers confinement in
such configurations. Our findings provide possible experimental measurements to
determine the interlayer coupling and the induced mass terms in graphene
bilayer based on conductance and band structure measurements.
