Abstract
We theoretically explore the control of the wave-vector filtering (WVF) effect in a hybrid magnetic-electric-barrier nanostructure, which can be experimentally realized by depositing a ferromagnetic (FM) stripe and a Schottky-metal (SM) stripe on top and bottom of a GaAs/Al\(_{\text {x}}\)Ga\(_{1-x}\)As heterostructure, respectively. It is shown that an obvious WVF effect appears in such a device. It is also shown that the degree of the WVF effect is related to the width and position of the SM stripe. In particular, the WVF effect can be tuned by the applied voltage to the SM stripe, and thus a manipulable momentum filter can be obtained for nanoelectronics applications.
