英文摘要	the quantum goos-hanchen shift for ballistic electrons is investigated in a parabolic potential well under a uniform vertical magnetic field. it is found that the goos-hanchen shift can be negative as well as positive, and becomes zero at transmission resonances. the beam shift depends not only on the incident energy and incidence angle, but also on the magnetic field and landau quantum number. based on these phenomena, we propose an alternative way to realize the spin beam splitter in the proposed spintronic device, which can completely separate spin-up and spin-down electron beams by negative and positive goos-hanchen shifts.
