摘要：

A theory of charge transport across the heterojunction potential barriers based on the electron energy conservation and on the quasiimpuls parallel component conservation is presented. A rectangular potential step, rectangular potential barrier and parabolic barrier of the space charge layer of a Np-heterojunction are investigated. The concept of effective barrier height is used to determine the domains of integration in the current density formulae. It is demonstrated that the ratio of electron effective masses together with the motion parallel to the heterointerface significantly affect the thermionic emission and tunneling.
