In this paper, we consider the ballistic transport of electrons propagating in the semiconductor superlattice with some angle relative to normal line for interfaces. Such propagation of electrons is characterized by a wave vector which can be decomposed in two components (the in‐plane component and the normal component). If the total energy of the electron is known, the in‐plane component can be easy recalculated into the angle of incidence using the simple analytical expression derived in the paper. The dependence of the transmissivity of electrons on the in‐plane wave vector has been computed. As a result, the angular distribution of the transmissivity is represented. Obtained results reveal that the transmissivity of electrons is strongly dependent on their angle of incidence. This relationship is characterized by slow oscillations or by sharp peaks depending on the energy of electrons. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
