  • Flux-quantum-modulated Kondo conductance in a multielectron quantum dot 
    Fühner, C.; Keyser, U.F.; Haug, Rolf J.; Reuter, D.; Wieck, A.D. (College Park, MD : American Physical Society, 2002)
    We investigate a lateral semiconductor quantum dot with a large number of electrons in the limit of strong coupling to the leads. A Kondo effect is observed and can be tuned in a perpendicular magnetic field. This Kondo ...
  • Phonons in InAs/AlAs single quantum dots observed by optical emission 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2005)
    Photoluminescence emission spectra of self-assembled single InAs/AlAs quantum dots with variable size reveal typical sharp lines below 1.8 eV, corresponding to transitions between fully confined states. Above this energy ...
  • Shot noise in self-assembled InAS quantum dots 
    Nauen, A.; Hapke-Wurst, I.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2002)
    We investigate the noise properties of a GaAs-AlAs-GaAs tunneling structure with embedded self-assembled InAs quantum dots in the single-electron tunneling regime. We analyze the dependence of the relative noise amplitude ...
