Conductance of disordered strain-induced graphene superlattices

We study the transmission and conductance of massless Dirac fermions through the strain-induced graphene superlattices (SGSLs). In this paper, the effect of strain fluctuations on the conductance of SGSLs is studied. We showed that the conductance of the SGSLs decreases with increasing the strength of strain fluctuations. Also, we study both the effects of negative and positive strains in presence of disorder. It is shown that, in the same condition, the conductance of a negative strain-induced superlattice is more than a superlattice with positive strain.
