Journal ArticleDOI
Valley-selective circular dichroism of monolayer molybdenum disulphide
Ting Cao,Gang Wang,Wen-Peng Han,Huiqi Ye,Chuanrui Zhu,Junren Shi,Qian Niu,Qian Niu,Ping-Heng Tan,Enge Wang,Baoli Liu,Ji Feng +11 more
TL;DR: It is shown, using first principles calculations, that monolayer molybdenum disulphide is an ideal material for valleytronics, for which valley polarization is achievable via valley-selective circular dichroism arising from its unique symmetry.
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
Superconductivity in the iron selenide K x Fe 2 Se 2 (0≤x≤1.0)
Jiangang Guo,Shifeng Jin,Gang Wang,Shunchong Wang,Kaixing Zhu,Tingting Zhou,Meng He,Xiaolong Chen +7 more
TL;DR: In this article, the superconductivity at above 30 K in a FeSe-layer compound K0.8Fe2Se2 (nominal composition) achieved by metal K intercalating in between FeSe layers was reported.
Journal ArticleDOI
Excitonic Linewidth Approaching the Homogeneous Limit in MoS 2 -Based van der Waals Heterostructures
Fabian Cadiz,E. Courtade,Cedric Robert,Gang Wang,Y. Shen,Hui Cai,T. Taniguchi,Kenji Watanabe,Hélène Carrère,D. Lagarde,M. Manca,Thierry Amand,Pierre Renucci,Sefaattin Tongay,Xavier Marie,B. Urbaszek +15 more
TL;DR: In this article, the authors show that encapsulation of monolayer MoS2 in hexagonal boron nitride can efficiently suppress the inhomogeneous contribution to the exciton linewidth, as they measure in photoluminescence and reflectivity a FWHM down to 2 meV at T=4
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.
