  • Coupling in concentric double quantum rings 
    Mühle, A.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2007)
    We designed a device consisting of two concentric quantum rings in a GaAsAlGaAs heterostructure. The outer ring is connected to leads while the inner ring is only capacitively coupled to the rest of the system. Measuring ...
  • Enhanced conductivity at the interface of Li2O:B2O3 nanocomposites: Atomistic models 
    Islam, Mazharul M.; Bredow, Thomas; Indris, Sylvio; Heitjans, Paul (College Park, ML : American Physical Society, 2007)
    A theoretical investigation at density-functional level of Li ion conduction at the interfaces in Li2O:B2O3 nanocomposites is presented. The structural disorder at the Li2O(111):B2O3(001) interface leads to reduced defect ...
  • Evaluating commercial moisture probes in reference solutions covering mineral to peat soil conditions 
    Dettmann, Ullrich; Bechtold, Michel (Washington, DC : Soil Science Society of America, 2018)
    Capacitance and time domain reflectometry (TDR) probes are frequently used for measurements of the volumetric soil water content. The measurement concept is based on the correlation between volumetric water content and ...
  • Ferrocene-1,1' -dithiol as molecular wire between Ag electrodes: The role of surface defects 
    Bredow, T.; Tegenkamp, Christoph; Pfnür, Herbert; Meyer, J.; Maslyuk, V.V.; Mertig, I. (College Park, MD : American Institute of Physics, 2008)
    The interaction of ferrocene- 1, 1' -dithiol (FDT) with two parallel Ag(111) surfaces has been theoretically studied at density-functional level. The effect of surface defects on the energetic and electronic structure was ...
  • Graphene-like metal-organic frameworks: Morphology control, optimization of thin film electrical conductivity and fast sensing applications 
    Hoppe, Bastian; Hindricks, Karen D.J.; Warwas, Dawid P.; Schulze, Hendrik A.; Mohmeyer, Alexander; Pinkvos, Tim J.; Zailskas, Saskia; Krey, Marc R.; Belke, Christopher; König, Sandra; Fröba, Michael; Haug, Rolf J.; Behrens, Peter (Cambridge : Royal Society of Chemistry, 2018)
    The metal-organic framework Cu-2,3,6,7,10,11-hexahydroxytriphenylene (Cu3hhtp2-MOF), a copper-based graphene-like framework, is one of the few MOFs featuring inherent electrical conductivity. Here, we investigate the ...
  • High frequency conductivity in the quantum Hall regime 
    Hohls, Frank; Zeitler, U.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)
    The frequency dependence of the longitudinal conductivity σxx for frequencies up to 6 GHz was measured. It was possible to access both the real part and the imaginary part of σxx which allowed to perform a new test of ...
  • 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 ...
  • Mesoporous tin-doped indium oxide thin films: Effect of mesostructure on electrical conductivity 
    Graberg, Till von; Hartmann, Pascal; Rein, Alexander; Gross, Silvia; Seelandt, Britta; Röger, Cornelia; Zieba, Roman; Traut, Alexander; Wark, Michael; Janek, Jürgen; Smarsly, Bernd M. (Bristol : Institute of Physics Publishing, 2011)
    We present a versatile method for the preparation of mesoporous tin-doped indium oxide (ITO) thin films via dip-coating. Two poly(isobutylene)-b- poly(ethyleneoxide) (PIB-PEO) copolymers of significantly different molecular ...
  • Modeling the influence of thermal modification on the electrical conductivity of wood 
    Brischke, Christian; Sachse, Kathrin A.; Welzbacher, Christian R. (Berlin : De Gruyter, 2014)
    A model has been developed aiming at the description of the effect of thermal modification on the electrical conductivity of wood. The intention was to calculate the moisture content (MC) of thermally modified timber (TMT) ...
  • Nanocrystalline versus microcrystalline Lo2O:B2O 3 composites: Anomalous ionic conductivities and percolation theory 
    Indris, Sylvio; Heitjans, Paul; Roman, H. Eduardo; Bunde, Armin (College Park, ML : American Physical Society, 2000)
    We study ionic transport in nano- and microcrystalline (1−x)Li2O:xB2O3 composites using standard impedance spectroscopy. In the nanocrystalline samples (average grain size of about 20 nm), the ionic conductivity σdc increases ...
  • Role of doping agent degree of sulfonation and casting solvent on the electrical conductivity and morphology of pedot:Spaes thin films 
    Tomasino, Daniela Valeria; Wolf, Mario; Farina, Hermes; Chiarello, Gianluca; Feldhoff, Armin; Ortenzi, Marco Aldo; Sabatini, Valentina (Basel : MDPI AG, 2021)
    Poly(3,4-ethylenedioxythiophene) (PEDOT) plays a key role in the field of electrically conducting materials, despite its poor solubility and processability. Various molecules and polymers carrying sulfonic groups can be ...
