Traverse electric field effect on wave vector filtering in a magnetically modulated semiconductor nanostructure
Abstract
We theoretically study the effect of traverse electric field on wave vector filtering (WVF) in a magnetically modulated nanostructure, which can be constructed by patterning ferromagnetic (FM) stripes on top and bottom of GaAs/AlxGa1-xAs heterostructure. Using the transfer matrix method, electric field-dependent transmission is calculated by using Weber function for electrons across the structure. We find that WVF efficiency is manipulable by adjusting direction or strength of electric field. Thus, an electrically-tunable momentum filtering device can be obtained.
