Radiative Pattern of Intralayer and Interlayer Excitons in Two-Dimensional WS2/WSe2 Heterostructure
Mohammed Adel Aly, Manan Shah, Lorenz Maximilian Schneider +4
Two-dimensional (2D) heterostructures (HS) formed by transition-metal dichalcogenide (TMDC) monolayers offer a unique platform for the study of intralayer and interlayer excitons a…
Controlled edge dependent stacking of WS2-WS2 Homo- and WS2-WSe2 Hetero-structures: A Computational Study
Kamalika Ghatak, Kyung Nam Kang, Eui-Hyeok Yang +1
Transition Metal Dichalcogenides (TMDs) are one of the most studied two-dimensional materials in the last 5-10 years due to their extremely interesting layer dependent properties.…
Spin-Layer- and Spin-Valley-Locking in CVD-Grown AA'- and AB-Stacked Tungsten-Disulfide Bilayers
Lorenz Maximilian Schneider, Jan Kuhnert, Simon Schmitt +10
Valley-selective optical selection rules and a spin-valley locking in transition-metal dichalcogenide (TMDC) monolayers are at the heart of "valleytronic physics", which exploits t…
Achieving Large, Tunable Strain in Monolayer Transition-Metal Dichalcogenides
Abdollah, M. Dadgar, Declan Scullion +7
We describe a facile technique based on polymer encapsulation to apply several percent controllable strains to monolayer and few-layer Transition Metal Dichalcogenides (TMDs). We u…
Influence of the Substrate Material on the Optical Properties of Tungsten Diselenide Monolayers
Sina Lippert, Lorenz Maximilian Schneider, Dylan Renaud +13
Monolayers of transition-metal dichalcogenides such as WSe2 have become increasingly attractive due to their potential in electrical and optical applications. Because the propertie…
