Investigations on unconventional aspects in the quantum Hall regime of narrow gate defined channels

J. Horas, A. Siddiki, J. Moser +2

We report on theoretical and experimental investigations of the integer quantized Hall effect in narrow channels at various mobilities. The Hall bars are defined electrostatically…

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…
