Cyclotron absorption in GaSb InAs GaSb quantum wells
Ivanov Yu. L., Kop'ev P. S., Suchalkin S. D., Ustinov V. M.
A splitting of the cyclotron-absorption line has been observed in a GaSb-InAs-GaSb quantum-well system. The behavior of the splitting was studied as the laser photon energy and the strength and direction of the applied magnetic field were varied. The results are explained on the basis of a model involving a lifting of spin degeneracy.
