| 摘要 | 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 sigma (+) and sigma (-) 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. |
