Ballistic Conductance Model of Bilayer Graphene Nanoribbon (BGN)

Ballistic conductance of Bilayer Graphene Nanoribbons (BGNs) is concerned in this paper. Mathematical model and numerical solution of BGNs ballistic conductance is introduced as well as its analytical model in the degeneracy limit. Our method indicates that near the neutrality point the non-degenerate approximation can be properly used. In contrast, out of this boundary condition it is estimated to work in the degenerate regime. Moreover, it confirms that BGN conductance is temperature dependence near the neutrality point also minimum conductance is depended on temperature which increases by increasing temperature but beyond the neutrality point conductance is independent of temperature. Presented model shows good agreement by published experimental data.
