  • Dynamical scaling of the quantum Hall plateau transition 
    Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Meisels, R.; Dybko, K.; Kuchar, F. (College Park, MD : American Physical Society, 2002)
    The dynamical scaling of the quantum Hall plateau phase transition in the frequency range 0.1-55 GHz was examined. A universal scaling function was observed, yielding a dynamical exponent 0.9 ± 0.2. The universal behavior ...
  • Effect of modulation-doping on luminescence properties of plasma assisted MBE-grown GaN/AIGaN quantum well 
    Kamata, N.; Klausing, H.; Fedler, F.; Mistele, D.; Aderhold, J.; Semchinova, O.K.; Graul, J.; Someya, T.; Arakawa, Y. (Cambridge : Cambridge University Press, 2004)
    In order to improve the crystal quality of GaN-based light emitting devices, photoluminescence (PL) characterization of below-gap states in plasma assisted MBE-grown GaN/AlGaN quantum well (QW) structures has been done by ...
  • Exciton fine structure and biexciton binding energy in single self-assembled InAs/AIAs quantum dots 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2006)
    The exciton and biexciton emissions of a series of single quantum dots of InAs in an AlAs matrix have been studied. These emissions consist of linear cross polarized doublets showing large values of both the biexciton ...
  • Phonon excitations of composite-fermion Landau levels 
    Schulze-Wischeler, F.; Hohls, Frank; Zeitler, U.; Reuter, D.; Wieck, A.D.; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    The phonon excitations of fractional quantum Hall (FQH) states at filling factors ν =1÷3,2÷5, 4÷7, 3÷5, 4÷3, and 5÷3 were investigated. The excitations were found to be based on Landau-level transitions of composite fermions ...
  • Spin-orbit coupling and anisotropy of spin splitting in quantum dots 
    Könemann, J.; Haug, Rolf J.; Maude, D.K.; Fal'Ko, V.I.; Altshuler, B.L. (College Park, MD : American Physical Society, 2005)
    In lateral quantum dots, the combined effect of both Dresselhaus and Bychkov-Rashba spin-orbit coupling is equivalent to an effective magnetic field ±BSO which has the opposite sign for sz=±1/2 spin electrons. When the ...
