| 摘要 | Abstract The electronic structures and absorption spectra of InAs1?x N x nanowires in the magnetic field are calculated via the combination of effective-mass theory and band anticrossing model, and the results exhibit the degenerate electron and hole states will be split by the magnetic field, which leads to the separation of σ + and σ ? absorption spectra. Moreover, the calculations demonstrate the exciton g factor g ex can undergo the transition from negative to positive with the size increasing, and g ex is almost independent of the magnetic field, while decreasing slightly by enhancing the nitrogen content of InAs1?x N x nanowires. |
