Anisotropic quantum Hall effect
Physical Review B, 1993A discussion of the transport properties of anisotropic Hall samples is presented. Such anisotropic samples can now be made by modulation-doped overgrowth on the cleaved edge of an ${\mathrm{Al}}_{\mathit{x}}$${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$As compositional superlattice.

Basically, the quantum Hall effect (QHE) has nothing to do with atomic physics. Semiconductors are normally used to observe this quantum phenomenon, and the 1023 atoms per cubic centimeter of a semiconductor represent such a complicated system of interacting atoms that its electronic properties are normally described by phenomenological quantities and ...

1The gap equation for the electron self-energy function is considered in the framework of (2 1 1)-dimensional quantum electrodynamics. The filling factor n for the quantum Hall effect is related to a free parameter l by considering the development of the gap equation.

Relativistic quantum Hall effect
Physical Review D, 1991Quantum electrodynamics in 2+1 dimensions (${\mathrm{QED}}_{2+1}$) at finite density and temperature is analyzed by reducing it to an effective (0+1)-dimensional theory. A realization of ${\mathrm{QED}}_{2+1}$ at finite density in the context of (planar) gapless semiconductors is suggested.

Abstract It is explained how plateaux are seen in the Hall conductance of two dimensional electron gases, at cryogenic temperatures, when the magnetic field is scanned from zero to ~10T. On a Hall plateau σxy = ne2/h, where n is integral, while the longitudinal conductance vanishes. This is the integral quantum Hall effect.

The history and the experimental conditions leading to the discovery of the quantum Hall effect are discussed with a view to compare and contrast with the classical version of the effect. Landau levels are obtained for electrons confined in two dimensions (2D) in the presence of a strong transverse magnetic field.

Quantum hall effect in graphene
2008 Conference on Precision Electromagnetic Measurements Digest, 2008Graphene is the first example of truly two-dimensional crystals - it's just one layer of carbon atoms [1,2]. It turns out that graphene is a gapless semiconductor with unique electronic properties resulting from the fact that charge carriers in graphene obey linear dispersion relation, thus mimicking massless relativistic particles. This results in the
