Abstract.

Using the Landauer formula approach, it is proven that minimal conductivity of order e2/h found experimentally in bilayer graphene is an intrinsic property. For the case of ideal crystals, the conductivity turns out to be equal to e2/2h per valley per spin. A zero-temperature shot noise in bilayer graphene is considered and the Fano factor is calculated. Its value 1–2/π is close to the value 1/3 found earlier for single-layer graphene.
