Query: Electronic structure and layer-resolved transmission of bilayer graphene
  nanoribbon in the presence of vertical fields   Electronic properties of bilayer graphene are distinct from both the
conventional two dimensional electron gas and monolayer graphene due to its
particular chiral properties and excitation charge carrier dispersions. We
study the effect of strain on the electronic structure, the edge-states and
charge transport of bilayer graphene nanoribbon at zero-temperature. We
demonstrate a valley polarized quantum Hall effect in biased bilayer graphene
when the system is subjected to a perpendicular magnetic field. In this system
a topological phase transition from a quantum valley Hall to a valley polarized
quantum Hall phase can occur by tuning the interplanar strain. Furthermore, we
study the layer-resolved transport properties by calculating the layer
polarized quantity by using the recursive Green's function technique and show
that the resulting layer polarized value confirms the obtained phases. These
predictions can be verified by experiments and our results demonstrate the
possibility for exploiting strained bilayer graphene in the presence of
external fields for electronics and valleytronics devices.
