| 英文摘要 | This paper theoretically investigates the orbital magnetization of electron-doped (n-type) semiconductor heterostructures and of hole-doped (p-type) bulk semiconductors, which are respectively described by a two-dimensional electron/hole hamiltonian with both the included rashba spin-orbit coupling and zeeman splitting terms. it is the zeeman splitting, rather than the rashba spin-orbit coupling, that destroys the time-reversal symmetry of the semiconductor systems and results in nontrivial orbital magnetization. the results show that the magnitude of the orbital magnetization per hole and the hall conductance in the p-type bulk semiconductors are about 10(-2)-10(-1) effective bohr magneton and 10(-1)-1 e(2)/h, respectively. however, the orbital magnetization per electron and the hall conductance in the n-type semiconductor heterostructures are too small to be easily observed in experiment. |
