|Abstract:||The dependence of the subband densities in a potential well with tunable symmetry on a weak in-plane magnetic field is investigated experimentally by analyzing Shubnikov-de Haas oscillations. We measure a strong carrier redistribution between the subbands, which is explained by individual magnetic-field-dependent density of states in different subbands rather than by the diamagnetic energy shift. The measured carrier redistribution is quantitatively explained considering the in-plane field in second-order perturbation theory.|
