Two-dimensional Mott-Hubbard electrons in an artificial honeycomb lattice
A. Singha, M. Gibertini, B. Karmakar +8
Electrons in artificial lattices enable explorations of the impact of repulsive Coulomb interactions in a tunable system. We have trapped two-dimensional electrons belonging to a g…
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…
