Abstract
A group of GaSb-InAs-GaSb quantum wells with 75-Å well thickness are studied via magnetotransport. A beating pattern in the Shubnikov-de Haas oscillation is observed. Analysis of the data yields two carrier densities and . Both are identified as electrons and are attributed to the population of the ground electron subband whose twofold spin degeneracy is lifted due to the lack of inversion symmetry of the system. A zero-field spin splitting of 3.5 meV is deduced from the electron densities. The evolution of the beating pattern with a tilted magnetic field is also discussed.
