Shubnikov - de haas effect in tilted magnetic fields in wide quantum well
Larkin, Ivan; Ujevic, S.; Wiedmann, S.; Gusev, G. M.; Portal, J. C.; Bakarov, A. K.Bilayer two-dimensional electron system in double quantum wells demonstrated oscillations of the symmetric–antisymmetric energy gap in the presence of the in-plane magnetic field [1] which has been attributed to Aharonov-Bohm interference effect between cyclotron orbits in different layers [2]. The charge distribution in a wide single quantum well is more subtle than the one in the double quantum well. Here th...
Landau levels in two and three-dimensional electron gases in a wide parabolic q...
Sergio,C.S.; Gusev,G.M.; Leite,J.R.; Olshanetskii,E.B.; Bykov,A.A.; Moshegov,N.T.; Bakarov,A.K.; Toropov,A.I.; Maude,D.K.; Estibals,O.; Portal,J.C.Shubnikov-de Haas oscillations are measured in a wide parabolic quantum well with 6 subbands in a tilted magnetic fi eld. We find two types of oscillations. The oscillations at low magnetic field are shifted towards higher fields with tilted angles, and can be attributed to the two-dimensional Landau state at the bottom subband. The position of the second type oscillations do not shift with tilted angles indica...
