  • Building blocks for future detectors: Silicon test masses and 1550 nm laser light 
    Schnabel, Roman; Britzger, M.; Brückner, F.; Burmeister, O.; Danzmann, Karsten; Dück, J.; Eberle, Tobias; Friedrich, Daniel; Lück, Harald; Mehmet, Moritz; Nawrodt, Ronny; Steinlechner, S.; Willke, Benno (Bristol : IOP Publishing Ltd., 2010)
    Current interferometric gravitational wave detectors use the combination of quasi-monochromatic, continuous-wave laser light at 1064 nm and fused silica test masses at room temperature. Detectors of the third generation, ...
  • Influence of the channel design on the heat and mass exchange of induction channel furnace 
    Baake, E.; Jakovics, A.; Pavlovs, S.; Kirpo, M. (Bingley : Emerald Group Publishing Ltd., 2011)
    Purpose - The purpose of this paper is to present in-depth numerical modelling of heat and mass exchange in industrial induction channel furnace (ICF). Design/methodology/approach - The turbulent heat and mass exchange in ...
  • Laser interferometry with translucent and absorbing mechanical oscillators 
    Friedrich, Daniel; Kaufer, Henning; Westphal, Tobias; Yamamoto, K.; Sawadsky, Andreas; Ya Khalili, F.; Danilishin, S.L.; Goßler, Stefan; Danzmann, Karsten; Schnabel, Roman (Bristol : IOP Publishing Ltd., 2011)
    The sensitivity of laser interferometers can be pushed into regimes that enable the direct observation of the quantum behaviour of mechanical oscillators. In the past, membranes with subwavelength thickness (thin films) ...
  • Low-temperature hysteresis in the field effect of bilayer graphene 
    Barthold, P.; Lüdtke, T.; Schmidt, H.; Haug, Rolf J. (Bristol : IOP Publishing Ltd., 2011)
    Hysteresis in the field effect of bilayer graphene is observed at a low temperature. We attribute this effect to charge traps in the substrate. When the sweep rate of the back-gate voltage is increased to higher values, ...
  • 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 ...
  • Multi-terminal magnetotransport measurements over a tunable graphene p-n junction created by AFM-nanomachining 
    Schmidt, H.; Smirnov, D.; Rode, J.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    An Atomic Force Microscope is used to alter one part of a single layer graphene sample locally. Transport experiments at low temperatures are then used to characterize the different parts independently with field effect ...
  • Spin noise spectroscopy in GaAs (110) quantum wells: Access to intrinsic spin lifetimes and equilibrium electron dynamics 
    Müller, Georg M.; Römer, Michael; Schuh, Dieter; Wegscheider, Werner; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2008)
    In this Letter, the first spin noise spectroscopy measurements in semiconductor systems of reduced effective dimensionality are reported. The nondemolition measurement technique gives access to the otherwise concealed ...
  • Temperature-dependent change of the fractal dimension of Cu dendrites on Cu(111) 
    Sprodowski, C.; Morgenstern, K. (Bristol : Institute of Physics Publishing, 2020)
    We investigate the shape of monatomic high Cu islands on a Cu(111) surface by variable-temperature scanning tunneling microscopy between 110 K and 240 K. Low temperature dendrites evolve towards more compact shapes at ...
