This paper studies the conductance of charge carriers through silicene-based superlattices consisting
of monolayer silicene by means of transfer matrix method. At first, we consider the ordered
superlattices and drive analytically the transmission probability of dirac fermions. We show that the
number of resonance picks increases with increasing the number of superlattice barriers. In order to
the best understand of the appearance of the picks, we exactly studied transmission properties of
the silicene superlattice. Also, the effect of disorder on the probability of transmission through the
system of various sizes is studied. The short-range correlated disorder is applied on the thickness of
electron doped silicene strips as quantum barriers which fluctuates around their mean values. We
show that the oscillating conductance as a function of barriers hight suppress with imposing the
disorder in the silicene superlattice. Also, the effect of structural parameters on the conductance of
the system are studied.
