Giant Valley-Zeeman Splitting from Spin-Singlet and Spin-Triplet Interlayer Excitons in WSe2/MoSe2 Heterostructure
Tianmeng Wang, Shengnan Miao, Zhipeng Li +9
Transition metal dichalcogenides (TMDCs) heterostructure with a type II alignment hosts unique interlayer excitons with the possibility of spin-triplet and spin-singlet states. How…
Momentum-Dark Intervalley Exciton in Monolayer Tungsten Diselenide Brightened via Chiral Phonon
Zhipeng Li, Tianmeng Wang, Chenhao Jin +13
Inversion symmetry breaking and three-fold rotation symmetry grant the valley degree of freedom to the robust exciton in monolayer transition metal dichalcogenides (TMDCs), which c…
Optical detection of Mott and generalized Wigner crystal states in WSe2/WS2 moiré superlattices
Emma C. Regan, Danqing Wang, Chenhao Jin +14
Moiré superlattices are emerging as a new route for engineering strongly correlated electronic states in two-dimensional van der Waals heterostructures, as recently demonstrated in…
Direct Observation of Gate Tunable Dark Trions in Monolayer WSe2
Zhipeng Li, Tianmeng Wang, Zhengguang Lu +11
Spin-forbidden intravalley dark exciton in tungsten-based transition metal dichalcogenides (TMDCs), owing to its unique spin texture and long lifetime, has attracted intense resear…
Emerging Photoluminescence from the Dark-Exciton Phonon Replica in Monolayer WSe2
Zhipeng Li, Tianmeng Wang, Chenhao Jin +13
Tungsten-based monolayer transition metal dichalcogenides host a long-lived dark exciton, an electron-hole pair in a spin-triplet configuration. The long lifetime and unique spin p…
Magnetic field induced splitting and polarization of monolayer-based valley exciton-polaritons
Nils Lundt, Evgeny Sedov, Max Waldherr +12
Atomically thin crystals of transition metal dichalcogenides are ideally suited to study the interplay of light-matter coupling, polarization and magnetic field effects. In this wo…
