| 中文摘要 | magnetotransport through quantum dot structures is investigated numerically via a scattering matrix technique. the results for two typical structures show that the magnetoconductance is strongly dependent on the quantum dot geometry. for the symmetric quantum dot structure, it is found that the magnetoconductance profiles exhibit irregular structures and the magnetic field plays a similar role to that of disorder in the electron transport. for the t-shaped quantum dot structure, the oscillations in the conductance are found to be completely suppressed and the quantized conductance plateaus are recovered in a strong magnetic field, which is attributed to the asymmetry of the structure geometry with respect to the right-and left-moving edge states. |
