Abstract
The transport properties of a disordered superlattice in the presence of an applied electric field are studied numerically using the transfer-matrix approach. The effect of disorder on the transmission coefficient as the length of the system and the field is varied is discovered. The existence of Stark ladders in a disordered system is also investigated. The paper concludes by considering transport in a superlattice with a weak magnetic field applied perpendicular to the electric field.Keywords
