Shubnikov-de Haas effect in tilted magnetic fields in wide quantum well
Larkin, Ivan; Ujevic, S.; Gusev, G. M.; Bakharov, A. K.; Portal, J. C.We study the magneto-resistance of a two-dimensional electron systems in a wide quantum well. We have considered two occupied subbands subjected to the tilted magnetic field in the regime of the magneto-inter-subband oscillations. We report on both experimental and theoretical studies of such a phenomenon and deduced information on the inter-subband energy gap in the presence of the in-plane magnetic field.
Visualization of wave function of quantum dot at fermi-edge singularity regime
Larkin, Ivan; Vdovin, E. E.; Khanin, Yu. N.; Ujevic, S.; Henini, M.We consider electron tunneling spectroscopy through an InAs quantum dot in a magnetic field applied perpendicular to the tunneling direction. We examine in details the anisotropic behavior of the amplitude and shape of the resonant peaks of I-V curves and concluded that (i) magnetotunneling spectroscopy at FES regime allows establishing position of resonant level in QD with high accuracy. (ii) The distinguishab...
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...
