| 英文摘要 | We have studied the electronic structure of vertically assembled quantum discs in a magnetic field with varying orientation using the effective mass approximation. we calculate the four energy levels of single-electron quantum discs and the two lowest energy levels of two-electron quantum discs in a magnetic field with varying orientation. the change of the magnetic field as an effective potential strongly modifies the electronic structure, leading to splittings of the levels and anticrossings between the levels. the calculated results also demonstrate the switching between the ground states with the total spin s = 0 and 1. the switching induces a qubit controlled by varying the orientation of the magnetic field. |
