摘要：

The Letter deals with the transport of relativistic electron through a quantum heterostructure in the presence of a constant bias voltage. The transmission coefficient associated to the relativistic moving through the considered system is computed using the transfer matrix formalism for piecewise constant potentials. The results are compared to those which correspond to the non-relativistic case, in which the Schrodinger equation is used. The comparison is performed for different values of the system length and the effect of the bias voltage is also studied. (C) 2013 Elsevier B.V. All rights reserved.
