Journal ArticleDOI

Quantized conductance of point contacts in a two-dimensional electron gas.

TL;DR: The first expenmental study of the resistance of ballistic pomt contacts m the 2DEG of high-mobihty GaAs-AlGaAs heterostructures is reported.
Journal ArticleDOI

Universal Optical Conductance of Graphite

TL;DR: The calculations within the Slonczewski-Weiss-McClure model explain well why the interplane hopping leaves the conductance of graphene sheets in graphite almost unchanged for photon energies between 0.1 and 0.6 eV, even though it significantly affects the band structure on the same energy scale.
Journal ArticleDOI

Quantum critical behaviour in a high- T c superconductor

TL;DR: It is demonstrated that the experimentally measured phase angle agrees precisely with the exponent of the optical conductivity, which points towards a quantum phase transition of an unconventional kind in the high-Tc superconductors.
Journal ArticleDOI

Superconductivity in MgB2: clean or dirty?

TL;DR: In this paper, the band disparity of the electronic structure is taken into account, not only in the superconducting state, but also in normal transport in MgB2.
Journal ArticleDOI

Determination of the gate-tunable band gap and tight-binding parameters in bilayer graphene using infrared spectroscopy

TL;DR: In this article, the authors present a compelling evidence for the opening of a bandgap in exfoliated bottom-gated bilayer graphene by fitting the gatevoltage-modulated infrared reflectivity spectra in a large range of doping levels with a tight-binding model and the Kubo formula.
