| 英文摘要 | The confined longitudinal-optical phonon-assisted tunneling through a parabolic quantum well with double barriers in a magnetic field perpendicular to the interfaces is studied theoretically based on a dielectric continuum model. the numerical results show that the applied magnetic field sharpens and heightens the phonon-assisted tunneling peaks in agreement with experimental observation. furthermore, the phonon-assisted magnetotunneling peaks shift towards the higher biases as the magnetic field increases. in contrast to the results for a rectangular quantum well, the ratio of peak to valley of the phonon-assisted tunneling is larger for the wider well case. it also indicates that the phonon-assisted tunneling current peaks can be easily observed for a wider parabolic quantum well.
