Wave vector filtering effect is explored for electrons in magnetically and electrically confined semiconductor heterostructure, which can be realized experimentally by depositing a ferromagnetic stripe Schottky metal parallel configuration on the surface of [Formula: see text] heterostructure. Adopting improved transfer matrix method to solve Schrödinger equation, electronic transmission coefficient calculated exactly, then wave efficiency obtained differentiating probability over longitudinal vector. An obvious appears, due an essentially two-dimensional process electron through magnetic nanostructure. Besides, associated closely with width, position externally applied voltage stripe, makes become controllable results manipulable momentum filter nanoelectronics.
