| 中文摘要 | by employing non-equilibrium green's function method, the mesoscopic fano effect modulated by rashba spin-orbit (so) coupling and external magnetic field has been elucidated for electron transport through a hybrid system composed of a quantum dot (qd) and an aharonov-bohm (ab) ring. the results show that the orientation of the fano line shape is modulated by the rashba spin-orbit interaction k(r)l variation, which reveals that the fano parameter q will be extended to a complex number, although the system maintains time-reversal symmetry (trs) under the rashba so interaction. furthermore, it is shown that the modulation of the external magnetic field, which is applied not only inside the frame, but also on the qd, leads to the fano resonance split due to zeeman effect, which indicates that the hybrid is an ideal candidate for the spin readout device.
