We study the conductance of graphene-based superlattice system in the presence of disorder. The system consists of a sequence of electron doped graphene as
wells together with hole doped graphene as barriers. The effect of
disorder in transmission probability through the system with
different sizes are studied. We show that in a disordered superlattice created separately by electron and hole regions, transmits mostly belongs to the quasiparticles that approach almost perpendicularly to the barrier interfaces. We calculate the conductivity of the finite size system in the presence of disorder and show that the conductivity decreases by increasing the system size and for specific cases, the conductance tends to a finite value.
