Near-unity light absorption in a monolayer WS2 van der Waals heterostructure cavity
Itai Epstein, Bernat Terrés, André J. Chaves +12
Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical response and exhibit strong light-matter interactions with lifetime-limited emission. While var…
Optical valley Hall effect for highly valley-coherent exciton-polaritons in an atomically thin semiconductor
Nils Lundt, Lukasz Dusanowski, Evgeny Sedov +11
Spin-orbit coupling is a fundamental mechanism that connects the spin of a charge carrier with its momentum. Likewise, in the optical domain, a synthetic spin-orbit coupling is acc…
Resolving spin, valley, and moiré quasi-angular momentum of interlayer excitons in WSe2/WS2 heterostructures
Chenhao Jin, Emma C. Regan, Danqing Wang +11
Moiré superlattices provide a powerful way to engineer properties of electrons and excitons in two-dimensional van der Waals heterostructures. The moiré effect can be especially st…
