We study the conductance of charge carriers through silicene and graphene based superlattices consisting of monolayer graphene and silicene by means of transfer matrix method. The system consists of a sequence of the silicene based barriers and graphene based wells. We consider the ordered superlattices and caculate the transmission probability of dirac fermions. We show that there is resonance picks in transmission probablity and the number of resonance picks increases with increasing the number of superlattice barriers. Also, the effect of structural parameters on the conductance of the system are studied. We compute numerically the conductance of the system and plot versus the hight of the potential barriers and show that it has the osilatory behavior. This behavior is in contrast to the schrodinger equation that conductance decay with increasing the barrier height.
