Abstract
In the present paper, generating randomly rough interfaces -with two different types of correlation functions and dissimilar characteristics and morphologies- have been considered. The correlation functions of generated interfaces have Gaussian and exponential forms and they have been used in heterostructures as the rough interfaces. The main purpose of the present research is to study the effect of interfaces roughness types on the coherent electron transport through heterostructures. In order to better evaluation, the transport properties of heterostructures have been obtained for both planar and rough interfaces. The results show that the transmission probability and current density have the lower values with considering the rough interfaces, in comparison with the planar ones. Moreover, it is found that the generated interfaces by exponential correlation function were rougher than that Gaussian ones.
