摘要：

In this paper, we study the electron effective Lande g-factor in the InAs quantum wire under an applied magnetic field and the Rashba effect. For this goal, we first present an analytic solution to one-particle Schrodinger equation in the presence of both magnetic field and spin-orbit interaction (SOI). Then, using the obtained energy levels, we study the electron effective Lande g-factor. It is found that: (i) The effective Lande g-factor decreases when magnetic field increases. (ii) By increasing the confinement length l(0). the electron g-factor decreases. (iii) By increasing the strength of SOI, the electron g-factor increases. (C) 2011 Elsevier Ltd. All rights reserved.
