Journal ArticleDOI
Colloquium : Excitons in atomically thin transition metal dichalcogenides
Gang Wang,Alexey Chernikov,Mikhail M. Glazov,Tony F. Heinz,Xavier Marie,Thierry Amand,Bernhard Urbaszek +6 more
TL;DR: In this article, the authors reviewed recent progress in understanding of the excitonic properties in monolayer transition metal dichalcogenides (TMDs) and future challenges are laid out.
Journal ArticleDOI
Giant Enhancement of the Optical Second-Harmonic Emission of WSe 2 Monolayers by Laser Excitation at Exciton Resonances
Gang Wang,Xavier Marie,Iann C. Gerber,Thierry Amand,Delphine Lagarde,L. Bouet,Marta L. Vidal,Andrea Balocchi,Bernhard Urbaszek +8 more
TL;DR: It is shown that the light-matter interaction in monolayer WSe_{2} is strongly enhanced when the incoming electromagnetic wave is in resonance with the energy of the exciton states of strongly Coulomb bound electron-hole pairs below the electronic band gap.
Journal ArticleDOI
Robust optical emission polarization in MoS2 monolayers through selective valley excitation
G. Sallen,L. Bouet,Xavier Marie,Gang Wang,Changxin Zhu,Wen-Peng Han,Yuan Lu,Ping-Heng Tan,Thierry Amand,Bilu Liu,Bernhard Urbaszek +10 more
TL;DR: In this paper, polarization resolved photoluminescence from monolayer polysilicon (MoS) was reported, a two-dimensional, noncentrosymmetric crystal with direct energy gaps at two different valleys in momentum space.
Journal ArticleDOI
Exciton radiative lifetime in transition metal dichalcogenide monolayers
Cedric Robert,D. Lagarde,Fabian Cadiz,Gang Wang,Benjamin Lassagne,Thierry Amand,Andrea Balocchi,Pierre Renucci,Sefaattin Tongay,Bernhard Urbaszek,Xavier Marie +10 more
TL;DR: In this paper, the exciton dynamics in transition metal dichalcogenide monolayers were investigated using time-resolved photoluminescence experiments performed with optimized time resolution.
Journal ArticleDOI
