  • Experimental setup for camera-based measurements of electrically and optically stimulated luminescence of silicon solar cells and wafers 
    Hinken, David; Schinke, Carsten; Herlufsen, Sandra; Schmidt, Arne; Bothe, Karsten; Brendel, Rolf (College Park, MD : American Institute of Physics, 2011)
    We report in detail on the luminescence imaging setup developed within the last years in our laboratory. In this setup, the luminescence emission of silicon solar cells or silicon wafers is analyzed quantitatively. Charge ...
  • 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 ...
  • Local droplet etching on InAlAs/InP surfaces with InAl droplets 
    Cao, Xin; Zhang, Yiteng; Ma, Chenxi; Wang, Yinan; Brechtken, Benedikt; Haug, Rolf J.; Rugeramigabo, Eddy P.; Zopf, Michael; Ding, Fei (New York, NY : American Inst. of Physics, 2022)
    GaAs quantum dots (QDs) grown by local droplet etching (LDE) have been studied extensively in recent years. The LDE method allows for high crystallinity, as well as precise control of the density, morphology, and size of ...
  • Results of the round robin calibration of reference solar cells within the PhotoClass project 
    Kröger, Ingo; Friedrich, Dirk; Winter, Stefan; Salis, Elena; Müllejans, Harald; Pavanello, Diego; Hohl-Ebinger, Jochen; Bothe, Karsten; Hinken, David; Dittmann, Sebastian; Friesen, Gabi; Bliss, Martin; Betts, Tom; Gottschalg, Ralph; Rimmelspacher, Lorentz; Stang, Johannes; Herrmann, Werner; Dubard, Jimmy (Les Ulis : EDP Sciences, 2018)
    An intercomparison of terrestrial photovoltaic (PV) calibrations was performed among a number of European calibration and testing laboratories that participated in the European Metrology Research Program (EMRP) project ...
  • 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 ...
  • 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 ...
