Electronic g factor and magnetotransport in InSb quantum wells
High mobility InSb quantum wells with tunable carrier densities are investigated by transport experiments in magnetic fields tilted with respect to the sample normal. We employ the coincidence method and the temperature dependence of the Shubnikov–de Haas oscillations and find a value for the effect...

| description | High mobility InSb quantum wells with tunable carrier densities are investigated by transport experiments in magnetic fields tilted with respect to the sample normal. We employ the coincidence method and the temperature dependence of the Shubnikov–de Haas oscillations and find a value for the effective g factor of |g^{*}|=35±4 and a value for the effective mass of m^{*}≈0.017m_{e}, where m_{e} is the free electron mass. Our measurements are performed in a magnetic field and a density range where the enhancement mechanism of the effective g factor can be neglected. Accordingly, the obtained effective g factor and the effective mass can be explained in a single-particle picture. Additionally, we explore the magnetotransport up to magnetic fields of 35 T and do not find features related to the fractional quantum Hall effect. |
