Anisotropic magnetic field dependence of many-body enhanced electron tunnelling through a quantum dot
E. E. Vdovin, Yu. N. Khanin, O. Makarovsky +6
We investigate the effect of an applied magnetic field on resonant tunneling of electrons through the bound states of self-assembled InAs quantum dots (QDs) embedded within an (AlG…
The quantum Hall ferromagnet at high filling factors: A magnetic field induced Stoner transition
B. A. Piot, D. K. Maude, M. Henini +7
Spin splitting in the integer quantum Hall effect is investigated for a series of AlGaAs/GaAs heterojunctions and quantum wells. Magnetoresistance measurements are pe…
Excited two-dimensional magnetopolaron states in quantum well of resonant tunnel junction
D. Yu. Ivanov, M. V. Chukalina, E. G. Takhtamirov +8
Tunnel spectroscopy is used to probe the electronic structure in GaAs quantum well of resonant tunnel junction over wide range of energies and magnetic fields normal to layers. Spi…
Development of the tunnelling gap in disordered 2D electron system with magnetic field: observation of the soft-hard gap transition
Yu. V. Dubrovskii, V. A. Volkov, L. Eaves +5
Magnetic field suppression of the tunneling between disordered 2D electron systems in GaAs around zero bias voltage has been studied. Magnetic field B normal to the layers induces…
Anisotropic magnetoresistance in a 2DEG in a quasi-random magnetic field
A. W. Rushforth, B. L. Gallagher, P. C. Main +4
We present magnetotransport results for a 2D electron gas (2DEG) subject to the quasi-random magnetic field produced by randomly positioned sub-micron Co dots deposited onto the su…
Hysteretic behavior and evidence for domain formation in a double-layer quantum Hall system at total filling factor 2
J. G. S. Lok, A. K. Geim, B. Tieke +5
We report anomalous behavior in a double-layer two dimensional hole gas (2DHG) at even integer filling factors which includes hysteresis in the longitudinal and Hall resistances an…
