Journal ArticleDOI
Quantized conductance of point contacts in a two-dimensional electron gas.
van Bart Wees,H. van Houten,C. W. J. Beenakker,J.G. Williamson,Leo P. Kouwenhoven,D. van der Marel,C. T. Foxon +6 more
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
D. van der Marel,D. van der Marel,H. J. A. Molegraaf,H. J. A. Molegraaf,Jan Zaanen,Zohar Nussinov,Zohar Nussinov,Fabrizio Carbone,Fabrizio Carbone,Andrea Damascelli,Hiroshi Eisaki,Martin Greven,P.H. Kes,Ming Li +13 more
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?
Igor Mazin,Ole Krogh Andersen,Ove Jepsen,Oleg V. Dolgov,Jens Kortus,Alexandre Avraamovitch Golubov,Alexey B. Kuzmenko,D. van der Marel +7 more
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.
