  • Energy dependence of quasiparticle relaxation in a disordered Fermi liquid 
    Schmidt, T.; König, P.; McCann, E.; Fal'ko, V.I.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)
    Direct measurement of the energy dependence of the inelastic decay rate τ(E) of a quasiparticle state in a disordered conductor was performed using resonant tunneling spectroscopy. Decay rate was obtained from the analysis ...
  • Evolutionary and genetic algorithms for design of metadevices working on electric dipole resonance 
    Melnikov, Roman; Baryshnikova, Kseniia V.; Petrov, Mihail; Ulyantsev, Vladimir; Evlyukhin, Andrey B.; Chichkov, Boris N. (Bristol : IOP Publishing Ltd., 2020)
    All-dielectric nanophotonics is a rapidly growing field of modern science. Metasurfaces and other planar devices based on all-dielectric nanoparticles lead to manage the light propagation at the nanoscale. Impressive effects ...
  • Hopping conductivity in the quantum Hall effect: Revival of universal scaling 
    Hohls, Frank; Zeitler, U.; Haug, Rolf J. (College Park, MD : American Physical Society, 2002)
    The temperature and electric field dependence of the conductivity in the quantum Hall effect (QHE) plateau transition for samples where no universal behavior is found in the conventional temperature dependent peak-width ...
  • Lifetime degradation mechanism in boron-doped Czochralski silicon 
    Voronkov, Vladimir V.; Falster, Robert; Batunina, A.V.; MacDonald, D.; Bothe, Karsten; Schmidt, J. (London : Elsevier Ltd., 2011)
    The recombination centre that emerges in boron- and oxygen-containing silicon was thought to be a complex of a substitutional boron atom Bs and an oxygen dimer O2. However in material co-doped with boron and phosphorus, ...
  • Low-temperature magnetostriction and distortions in the rare-earth Laves phases 
    Politova, G.; Ganin, M.; Kaminskaya, T.; Mikhailova, A.; Nacke, B.; Filimonov, A.; Burkhanov, G. (Bristol : Institute of Physics Publishing, 2019)
    The effects of partial substitution of dysprosium in Tb0.2Dy0.8Co2 by terbium and gadolinium on the structure and magnetic properties have been studied. Two compositions, Tb0.3Dy0.7Co2 and Tb0.2Dy0.7Gd0.1Co2 have been ...
  • Modeling of photoluminescence in laser-based lighting systems 
    Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, Wash. : SPIE, 2017)
    The development of laser-based lighting systems has been the latest step towards a revolution in illumination technology brought about by solid-state lighting. Laser-activated remote phosphor systems produce white light ...
  • RKKY interaction in a chirally coupled double quantum dot system 
    Heine, A.W.; Tutuc, D.; Zwicknagl, G.; Schuh, D.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    The competition between the Kondo effect and the Ruderman-Kittel-Kasuya- Yoshida (RKKY) interaction is investigated in a double quantum dots system, coupled via a central open conducting region. A perpendicular magnetic ...
  • Spin and mass excitations in the doped multiple spin exchange model on a triangular lattice: 3He on graphite 
    Seki, K.; Shirakawa, T.; Ohta, Y. (Bristol : IOP Publishing Ltd., 2009)
    Using an exact-diagonalization technique on small clusters, we calculate the spin and density excitation spectra as well as the temperature dependence of the specific heat for the triangular-lattice t-J model with the ...
  • Strongly temperature dependent resistance of meander-patterned graphene 
    Vasileva, G.Y.; Smirnov, D.; Vasilyev, Y.B.; Nestoklon, M.O.; Averkiev, N.S.; Novikov, S.; Kaya, I.I.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2017)
    We have studied the electronic properties of epitaxial graphene devices patterned in a meander shape with the length up to a few centimeters and the width of few tens of microns. These samples show a pronounced dependence ...
