Counterflow of electrons in two isolated quantum point contacts
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We study the interaction between two adjacent but electrically isolated quantum point contacts (QPCs). At high enough source-drain bias on one QPC, the drive QPC, we detect a finit…

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…
