| 英文摘要 | We have studied a two-electron quantum dot molecule in a magnetic field. the electron interaction is treated accurately by the direct diagonalization of the hamiltonian matrix. we calculate two lowest energy levels of the two-electron quantum dot molecule in a magnetic field. our results show that the electron interactions are significant, as they can change the total spin of the two-electron ground state of the system by adjusting the magnetic field between s = 0 and s = 1. the energy difference deltae between the lowest s = 0 and s = 1 states is shown as a function of the axial magnetic field. we found that the energy difference between the lowest s = 0 and s = 1 states in the strong-b s = 0 state varies linearly. our results provide a possible realization for a qubit to be fabricated by current growth techniques. |
