Characterization of individual layers in a bilayer electron system produced in a wide quantum well
S. I. Dorozhkin, A. A. Kapustin, I. B. Fedorov +3
Here we report on a transparent method to characterize individual layers in a double-layer electron system which forms in a wide quantum well and to determine their electron densit…
Microwave-Induced Oscillations in the Magnetocapacitance: Direct Evidence for Non-equilibrium Occupation of Electronic States
S. I. Dorozhkin, A. A. Kapustin, V. Umansky +2
In a two-dimensional electron system, microwave radiation may induce giant resistance oscillations. Their origin has been debated controversially and numerous mechanisms based on v…
Spin susceptibility and polarization field in a dilute two-dimensional electron system in (111) silicon
A. A. Kapustin, A. A. Shashkin, V. T. Dolgopolov +3
We find that the polarization field, B_chi, obtained by scaling the weak-parallel-field magnetoresistance at different electron densities in a dilute two-dimensional electron syste…
Strongly enhanced effective mass in dilute two-dimensional electron systems: System-independent origin
A. A. Shashkin, A. A. Kapustin, E. V. Deviatov +2
We measure the effective mass in a dilute two-dimensional electron system in (111)-silicon by analyzing temperature dependence of the Shubnikov-de Haas oscillations in the low-temp…
Evidence for the Luttigger liquid density of states in transport across the incompressible stripe at fractional filling factors
E. V. Deviatov, A. A. Kapustin, V. T. Dolgopolov +3
We experimentally investigate transport across the incompressible stripe at the sample edge in the fractional quantum Hall effect regime at bulk filling factors and …
Equilibration between edge states in the fractional quantum Hall effect regime at high imbalances
E. V. Deviatov, A. A. Kapustin, V. T. Dolgopolov +3
We experimentally study equilibration between edge states, co-propagating at the edge of the fractional quantum Hall liquid, at high initial imbalances. We find an anomalous increa…
