    • Half adder capabilities of a coupled quantum dot device 

      Pfeffer, P; Hartmann, F; Neri, I; Schade, A; Emmerling, M; Kamp, M; Gammaitoni, L; Hoefling, Sven; Worschech, L (2016-05-27) - Journal article
      In this paper we demonstrate two realizations of a half adder based on a voltage-rectifying mechanism involving two Coulomb-coupled quantum dots. First, we examine the ranges of operation of the half adder's individual ...
    • Optical probing of the Coulomb interactions of an electrically pumped polariton condensate 

      Klaas, M.; Mandal, S.; Liew, T. C. H.; Amthor, M.; Klembt, S.; Worschech, L; Schneider, C.; Höfling, Sven (2017-04-10) - Journal article
      We report on optical probing of the Coulomb interactions in an electrically driven exciton-polariton laser. By positioning a weak non-resonant Gaussian continuous wave-beam with a diameter of 2 μm inside an electrical ...
    • Optical tuning of the charge carrier type in the topological regime of InAs/GaSb quantum wells 

      Knebl, G; Pfeffer, P; Schmid, S; Kamp, M; Bastard, G; Batke, E; Worschech, L; Hartmann, F; Höfling, Sven (2018-07-16) - Journal article
      We study the optical tunability of the charge carrier type in InAs/GaSb double quantum wells with its type-II broken band alignment and inverted band structure. Under constant optical excitation, the majority charge carrier ...
