Quantum Hall Effect (QHE) A Personal View on the Discovery, Physics and Applications of this Quantum Effect
The birthday of the quantum Hall effect (QHE) can be fixed very accurately. It was the night of the 4th to the 5th of February 1980 at around 2 a.m. during an experiment at the High Magnetic Field Laboratory in Grenoble. The research topic included the characterization of the electronic transport of silicon field effect transistors. How can one improve the mobility of these devices? Which scatt...
متن کاملGiant magneto-conductance in twisted carbon nanotubes
Using the Landauer-Büttiker formalism, we calculate the effect of structural twist on electron transport in conducting carbon nanotubes. We demonstrate that even a localized region of twist scatters the propagating π electrons and induces the opening of a (pseudo-) gap near the Fermi level. The subsequent conductance reduction may be compensated by an applied axial magnetic field, leading to a ...

15 صفحه اولQuantum Hall Effect as a Resistance Standard
In a two-dimensional electron gas system, the Hall resistance at low temperatures and in strong magnetic field has plateaus as a function of the number of electrons that can be linked to natural constants as RH = h/ie. Due to the high precision of the measurement, the quantization of the Hall resistance is now used as the primary standard of resistance. The paper describes the use of quantum Ha...
