Based on the Anderson tight-binding model, the electronic properties of disordered bilayer
graphene are investigated. Our numerical results show that electrons in bilayer graphene
with monolayer disorder (MDBG) exhibit a peculiar behavior that is quite different from that in
bilayer graphene with bilayer disorder (BDBG). With the increase of disorder, BDBG
becomes an insulating disordered two-dimensional (2D) electron system. In the case of
monolayer disorder, however, the energy spectrum has strongly localized tail states and a …
