    • Cascaded emission of single photons from the biexciton in monolayered WSe2 

      He, Yu-Ming; Iff, Oliver; Baumann, Vasilij; Davanco, Marcelo; Srinivasan, Kartik; Höfling, Sven; Schneider, Christian (2016-11-10) - Journal article
      Monolayers of transition metal dichalcogenide materials emerged as a new material class to study excitonic effects in solid state, as they benefit from enormous Coulomb correlations between electrons and holes. Especially ...
    • Deterministic coupling of quantum emitters in WSe2 monolayers to plasmonic nanocavities 

      Iff, Oliver; Lundt, Nils; Betzold, Simon; Tripathi, Laxmi Narayan; Emmerling, Monika; Tongay, Sefaattin; Lee, Young Jin; Kwon, Soon Hong; Höfling, Sven; Schneider, Christian (2018-09-20) - Journal article
      We discuss coupling of site-selectively induced quantum emitters in exfoliated monolayers of WSe2 to plasmonic nanostructures. Gold nanorods of 20 nm-240 nm size, which are arranged in pitches of a few micrometers on a ...
    • Room temperature Tamm-Plasmon exciton-polaritons with a WSe2 monolayer 

      Lundt, Nils; Klembt, Sebastian; Cherotchenko, Evgeniia; Betzold, Simon; Iff, Oliver; Nalitov, Anton V.; Klaas, Martin; Dietrich, Christof P.; Kavokin, Alexey V.; Höfling, Sven; Schneider, Christian (2016-10-31) - Journal article
      Solid state cavity quantum electrodynamics is a rapidly advancing field which explores the frontiers of light-matter coupling. Metal-based approaches are of particular interest in this field, since they carry the potential ...
    • Spontaneous emission enhancement in strain-induced WSe2 monolayer-based quantum light sources on metallic surfaces 

      Tripathi, Laxmi Narayan; Iff, Oliver; Betzold, Simon; Dusanowski, Łukasz; Emmerling, Monika; Moon, Kihwan; Lee, Young Jin; Kwon, Soon Hong; Höfling, Sven; Schneider, Christian (2018-05-16) - Journal article
      Atomic monolayers of transition metal dichalcogenides represent an emerging material platform for the implementation of ultracompact quantum light emitters via strain engineering. In this framework, we discuss experimental ...
    • Substrate engineering for high quality emission of free and localized excitons from atomic monolayers in hybrid architectures 

      Iff, Oliver; He, Yu-Ming; Lundt, Nils; Stoll, Sebastian; Stoll, Sebastian; Baumann, Vasilij; Höfling, Sven; Schneider, Christian (2017-06-13) - Journal article
      Atomic monolayers represent a novel class of materials to study localized and free excitons in two dimensions and to engineer optoelectronic devices based on their significant optical response. Here, we investigate the ...
