Journal ArticleDOI
Observation of biexcitons in monolayer WSe2
Yumeng You,Yumeng You,Xiao-Xiao Zhang,Timothy C. Berkelbach,Mark S. Hybertsen,David R. Reichman,Tony F. Heinz,Tony F. Heinz +7 more
TL;DR: In this paper, strong many-body Coulomb interactions were shown to be strong enough to create four-body biexcitonic states in monolayer transition metal dichalcogenides.
Journal ArticleDOI
Experimental Evidence for Dark Excitons in Monolayer WSe 2
TL;DR: The experimental findings are consistent with theoretical predictions of spin-polarized conduction and valence bands at the K point of the Brillouin zone, with the minimum gap occurring between bands of opposite electron spin.
Journal ArticleDOI
Magnetic brightening and control of dark excitons in monolayer WSe2
Xiao-Xiao Zhang,Ting Cao,Zhengguang Lu,Yu-Chuan Lin,Fan Zhang,Ying Wang,Zhiqiang Li,James Hone,Joshua A. Robinson,Dmitry Smirnov,Steven G. Louie,Steven G. Louie,Tony F. Heinz +12 more
TL;DR: It is shown how an in-plane magnetic field can brighten the dark excitons in monolayer WSe2 and permit their properties to be observed experimentally and the fine spin-splitting at the conduction band edges is revealed.
Journal ArticleDOI
Tailoring the Electronic Structure in Bilayer Molybdenum Disulfide via Interlayer Twist
Arend M. van der Zande,Jens Kunstmann,Alexey Chernikov,Daniel Chenet,Yumeng You,Xiao-Xiao Zhang,Pinshane Y. Huang,Timothy C. Berkelbach,Lei Wang,Fan Zhang,Mark S. Hybertsen,Mark S. Hybertsen,David A. Muller,David R. Reichman,Tony F. Heinz,James Hone +15 more
TL;DR: Electronic structure calculations show the interlayer separation changes with twist due to repulsion between sulfur atoms, resulting in shifts of the indirect optical transition energies.
Journal ArticleDOI
Energy Transfer from Quantum Dots to Graphene and MoS2: The Role of Absorption and Screening in Two-Dimensional Materials
Archana Raja,Andrés Montoya−Castillo,Johanna Zultak,Xiao-Xiao Zhang,Ziliang Ye,Cyrielle Roquelet,Daniel Chenet,Arend M. van der Zande,Pinshane Y. Huang,Steffen Jockusch,James Hone,David R. Reichman,Louis E. Brus,Tony F. Heinz,Tony F. Heinz +14 more
TL;DR: The authors' measurements reveal contrasting trends in the NRET rate from the quantum dot to the van der Waals material as a function of thickness, which increases significantly with increasing layer thickness of graphene, but decreases with increasing thickness of MoS2 layers.
