  • 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 ...
  • Interplay of Electron and Nuclear Spin Noise in n -Type GaAs 
    Berski, Fabian; Hübner, Jens; Oestreich, Michael; Ludwig, Arne; Wieck, A.D.; Glazov, Mikhail (College Park, MD : American Physical Society, 2015)
    We present spin-noise spectroscopy measurements on an ensemble of donor-bound electrons in ultrapure GaAs:Si covering temporal dynamics over 6 orders of magnitude from milliseconds to nanoseconds. The spin-noise spectra ...
  • Single photon emission from ODT passivated near-surface GaAs quantum dots 
    Cao, Xin; Yang, Jingzhong; Li, Pengji; Zhang, Yiteng; Rugeramigabo, Eddy P.; Brechtken, Benedikt; Haug, Rolf J.; Zopf, Michael; Ding, Fei (Melville, NY : American Inst. of Physics, 2021)
    Epitaxially grown semiconductor quantum dots are promising candidates for pure single photon and polarization-entangled photon pair emission. Excellent optical properties can typically be ensured only if these so-called ...
  • 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 ...
  • Thickness uniformity measurements and damage threshold tests of large-area GaAs/AlGaAs crystalline coatings for precision interferometry 
    Koch, P.; Cole, G.D.; Deutsch, C.; Follman, D.; Heu, P.; Kinley-Hanlon, M.; Kirchhoff, R.; Leavey, S.; Lehmann, J.; Oppermann, P.; Rai, A.K.; Tornasi, Z.; Wöhler, J.; Wu, D.S.; Zederbauer, T.; Lück, H. (Washington, DC : OSA - The Optical Society, 2019)
    Precision interferometry is the leading method for extremely sensitive measurements in gravitational wave astronomy. Thermal noise of dielectric coatings poses a limitation to the sensitivity of these interferometers. To ...
  • Ultrahigh bandwidth spin noise spectroscopy: Detection of large g-factor fluctuations in highly-n-doped GaAs 
    Berski, Fabian; Kuhn, Hendrik; Lonnemann, Jan G.; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2013)
    We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing a sophisticated scheme of pulse trains from ultrafast laser oscillators as an optical ...
