Filling factor dependence of the fractional quantum Hall effect gap
V. S. Khrapai, A. A. Shashkin, M. G. Trokina +5
We directly measure the chemical potential jump in the low-temperature limit when the filling factor traverses the nu = 1/3 and nu = 2/5 fractional gaps in two-dimensional (2D) ele…
Direct measurements of the fractional quantum Hall effect gaps
V. S. Khrapai, A. A. Shashkin, M. G. Trokina +5
We measure the chemical potential jump across the fractional gap in the low-temperature limit in the two-dimensional electron system of GaAs/AlGaAs single heterojunctions. In the f…
Spin gap in the 2D electron system of GaAs/AlGaAs single heterojunctions in weak magnetic fields
V. S. Khrapai, A. A. Shashkin, E. L. Shangina +4
We study the interaction-enhanced spin gaps in the two-dimensional electron gas confined in GaAs/AlGaAs single heterojunctions subjected to weak magnetic fields. The values are obt…
Direct measurements of the spin and the cyclotron gaps in a 2D electron system in silicon
V. S. Khrapai, A. A. Shashkin, V. T. Dolgopolov
Using magnetocapacitance data in tilted magnetic fields, we directly determine the chemical potential jump in a strongly correlated two-dimensional electron system in silicon when…
