Properties of a 2D electron gas with lifted spectral degeneracy
Bychkov Yu. A. , Rashba E. I.
The properties of a 2D electron gas in which the twofold spin degeneracy of the spectrum has been lifted by a perturbation Hso = a[5xk]v are analyzed. The coefficient a is found from experimental data reported recently by Stein et al. and Stormer et al. on combined and cyclotron resonances at a heterojunction. The magnetic susceptibility is also studied.
