    • openAccess   Directed emission of CdSe nanoplatelets originating from strongly anisotropic 2D electronic structure 

      Scott, Riccardo; Heckmann, Jan; Prudnikau, Anatol V.; Antanovich, Artsiom; Mikhailov, Aleksandr; Owschimikow, Nina; Artemyev, Mikhail V.; Climente, Juan I.; Woggon, Ulrike; Grosse, Nicolai B.; Achtstein, Alexander W. Nature Publishing Group (2017)
      ntrinsically directional light emitters are potentially important for applications in photonics including lasing and energy-efficient display technology. Here, we propose a new route to overcome intrinsic efficiency ...

    • closedAccess   Directed Two-Photon Absorption in CdSe Nanoplatelets Revealed by k‑Space Spectroscopy 

      Heckmann, Jan; Scott, Riccardo; Prudnikau, Anatol V.; Antanovich, Artsiom; Owschimikow, Nina; Artemyev, Mikhail V.; Climente, Juan I.; Woggon, Ulrike; Grosse, Nicolai B.; Achtstein, Alexander W. American Chemical Society (2017)
      We show that two-photon absorption (TPA) is highly anisotropic in CdSe nanoplatelets, thus promoting them as a new class of directional two-photon absorbers with large cross sections. Comparing two-dimensional k-space ...

    • openAccess   Tuning intraband and interband transition rates via excitonic correlation in low-dimensional semiconductors 

      Planelles, Josep; Achtstein, Alexander W.; Scott, Riccardo; Owschimikow, Nina; Woggon, Ulrike; Climente, Juan I. ACS Publications (2018-08)
      We show that electron-hole correlation can be used to tune interband and intra- band optical transition rates in semiconductor nanostructures with at least one weakly confined direction. The valence-to-conduction band ...
