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.
