Using transfer–matrix method, this paper has investigated electronic transport properties of charge carriers in monolayer and bilayer graphene superlattices modulated by a homogeneous electric field. It is found that current density as a function of external field depends on the Fermi energy and the external field showing an oscillatory behavior. In other words, the current density in monolayer and bilayer graphene superlattices can be controlled by changing either the external field or the Fermi energy. Meanwhile, the graphene superlattice displays a negative differential resistance for some ranges of the external field. Furthermore, the current density raises monotonically by increasing the external field.<\div>

The influence of bulk donor and acceptor traps on electrical behavior of p+n photodiode based on InSb, is modeled. Theeffects of different trap types with different energy level on the dark current level, recombination rate, and electric field profile at 77Kare investigated. Our results show that the bulk acceptor traps with energy level near valence band significantly increase the darkcurrent and reduce the electric field. We also show that the acceptor traps in bulk increase recombination rate<\div>
