Using the density functional theory, we investigated the geometric and electronic structures of bilayer graphene containing asymmetric tensile strain between the layers. Our calculation clarified that the atomic density difference between the layers leads to the Dirac point shift, causing the charge redistribution between the layers. A carrier density investigation reveals that the carrier density shows the inhomogeneous distribution through the layers.
