Journal ArticleDOI
Room-temperature Tamm-plasmon exciton-polaritons with a WSe2 monolayer.
Nils Lundt,Sebastian Klembt,E. D. Cherotchenko,Simon Betzold,Oliver Iff,Anton Nalitov,Martin Klaas,Christof P. Dietrich,Alexey Kavokin,Sven Höfling,Sven Höfling,Christian Schneider +11 more
TL;DR: A Tamm-plasmon-polariton structure is implemented and the coupling to a monolayer of WSe2, hosting highly stable excitons is studied, featuring an anti-crossing between the exciton and photon modes with a Rabi-splitting of 23.5 meV.
Journal ArticleDOI
Cascaded emission of single photons from the biexciton in monolayered WSe 2
Yu-Ming He,Yu-Ming He,Oliver Iff,Nils Lundt,Vasilij Baumann,Marcelo Davanco,Kartik Srinivasan,Sven Höfling,Sven Höfling,Christian Schneider +9 more
TL;DR: This work unambiguously demonstrate the existence of a localized biexciton in a monolayer of WSe2, which triggers an emission cascade of single photons, and paves the way to a new generation of quantum optics experiments with two-dimensional semiconductors.
Journal ArticleDOI
Spontaneous Emission Enhancement in Strain-Induced WSe2 Monolayer-Based Quantum Light Sources on Metallic Surfaces
Laxmi Narayan Tripathi,Oliver Iff,Simon Betzold,Ł. Dusanowski,Monika Emmerling,Kihwan Moon,Youngjin Lee,Soon-Hong Kwon,Sven Höfling,Sven Höfling,Christian Schneider +10 more
TL;DR: In this paper, a strain induced single photon source using a WSe2 monolayer on a silver substrate, coated with a very thin dielectric layer, is described.
Journal ArticleDOI
Strain-Tunable Single Photon Sources in WSe2 Monolayers.
Oliver Iff,Davide Tedeschi,Javier Martín-Sánchez,Magdalena Moczała-Dusanowska,Sefaattin Tongay,Kentaro Yumigeta,Javier Taboada-Gutiérrez,Matteo Savaresi,Armando Rastelli,Pablo Alonso-González,Sven Höfling,Sven Höfling,Rinaldo Trotta,Christian Schneider +13 more
TL;DR: It is demonstrated that strain fields exerted by the piezoelectric device can be used to tune the energy of localized excitons in WSe2 up to 18 meV in a reversible manner, while leaving the single photon purity unaffected over a wide range.
Journal ArticleDOI
The interplay between excitons and trions in a monolayer of MoSe2
Nils Lundt,E. D. Cherotchenko,Oliver Iff,Xi Fan,Yuxia Shen,Pierre Bigenwald,Alexey Kavokin,Alexey Kavokin,Sven Höfling,Sven Höfling,Christian Schneider +10 more
TL;DR: In this article, the impact of a free carrier reservoir on the optical properties of excitonic and trionic complexes in a MoSe2 monolayer at cryogenic temperatures was investigated.
