Low-frequency noise of quantum point contacts in the ballistic and quantum Hall regime
Autor: C. Dekker, R. Eppenga, A.J. Scholten, C. T. Foxon, F. Liefrink, H. van Houten
Publikováno v: Physica B.Condensed matter 175(1-3), 213-216. (1991)
The low-frequency resistance noise of quantum point contacts is shown to be dominated by fluctuations in the electrostatic potential. Both in the ballistic and in the quantum Hall regime, the noise is strongly suppressed if the conductance is quantiz

Magnetic field effects on switching noise in a quantum point contact
Autor: Jaap I. Dijkhuis, H. van Houten, A.J. Scholten, Bruce W. Alphenaar, C. T. Foxon, F. Liefrink, C. Dekker
Publikováno v: Physical review B.Condensed matter and materials physics 46(23), 15523-15525. (1992)
We extend a previous study of the quantum-size effect on switching noise in a GaAs/${\mathrm{Al}}_{\mathit{x}}$${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$As quantum point contact in zero magnetic field to the quantum Hall regime. The experim
