Journal ArticleDOI
Low-temperature photocarrier dynamics in monolayer MoS2
TL;DR: In this paper, the authors report on scanning Raman and on temperature-dependent photoluminescence measurements on single-layer MoS2 flakes prepared by exfoliation.
Journal ArticleDOI
Coulomb engineering of the bandgap and excitons in two-dimensional materials
Archana Raja,Andrey Chaves,Andrey Chaves,Jaeeun Yu,Ghidewon Arefe,Heather M. Hill,Heather M. Hill,Albert F. Rigosi,Albert F. Rigosi,Timothy C. Berkelbach,Philipp Nagler,Christian Schüller,Tobias Korn,Colin Nuckolls,James Hone,Louis E. Brus,Tony F. Heinz,Tony F. Heinz,Tony F. Heinz,David R. Reichman,Alexey Chernikov,Alexey Chernikov +21 more
TL;DR: By engineering the surrounding dielectric environment, one can tune the electronic bandgap and the exciton binding energy in monolayers of WS2 and WSe2 by hundreds of meV, as an initial step towards the creation of diverse lateral junctions with nanoscale resolution.
Journal ArticleDOI
Excitonic linewidth and coherence lifetime in monolayer transition metal dichalcogenides.
Malte Selig,Gunnar Berghäuser,Archana Raja,Philipp Nagler,Christian Schüller,Tony F. Heinz,Tobias Korn,Alexey Chernikov,Alexey Chernikov,Ermin Malic,Andreas Knorr +10 more
TL;DR: It is shown that the excitonic coherence lifetime is determined by phonon-induced intravalley scattering and intervalley scattering into dark exciton states, and in particular, in WS2, exciton relaxation processes involving phonon emission into lower-lying dark states that are operative at all temperatures.
Journal ArticleDOI
Resonant internal Quantum transitions and femtosecond radiative decay of excitons in monolayer WSe2
C. Poellmann,Philipp Steinleitner,U. Leierseder,Philipp Nagler,Gerd Plechinger,Michael Porer,Rudolf Bratschitsch,Christian Schüller,Tobias Korn,Rupert Huber +9 more
TL;DR: In this article, the 1s-2p resonance of 1s A excitons in a single-layer WSe2 was analyzed and the decay dynamics of small-momentum exciton decay was shown to be ultrafast.
Journal ArticleDOI
Trion fine structure and coupled spin-valley dynamics in monolayer tungsten disulfide.
Gerd Plechinger,Philipp Nagler,Ashish Arora,Robert Schmidt,Alexey Chernikov,Andrés Granados del Águila,Peter C. M. Christianen,Rudolf Bratschitsch,Christian Schüller,Tobias Korn +9 more
TL;DR: In photoluminescence and in energy-dependent Kerr rotation measurements, the authors are able to resolve two different trion states, which they interpret as intravalley and intervalley trions.
