Layer-Hybridized Wigner Crystals in MoSe2/WS2 Moiré Superlattice
Tianyi Ouyang, Yuze Meng, Li Yan +11
Transition metal dichalcogenide moiré heterobilayers with type-II band alignment provide a versatile platform for layer-polarized generalized Wigner crystals, in which strong Coulo…
Exciton-polaron Umklapp scattering in Wigner crystals
Erfu Liu, Matthew Wilson, Jenny Hu +9
Strong Coulomb interactions in two-dimensional (2D) semiconductors give rise to tightly bound excitons, exciton polarons, and correlated electronic phases such as Wigner crystals (…
Brightening interlayer excitons by electric-field-driven hole transfer in bilayer WSe2
Tianyi Ouyang, Erfu Liu, Soonyoung Cha +8
We observe the interlayer A1s^I, A2s^I, and B1s^I excitons in bilayer WSe2 under applied electric fields using reflectance contrast spectroscopy. Remarkably, these interlayer excit…
Enhancing resonant second harmonic generation in bilayer WSe2 by layer-dependent exciton-polaron effect
Soonyoung Cha, Tianyi Ouyang, Takashi Taniguchi +3
Two-dimensional (2D) materials serve as exceptional platforms for controlled second harmonic generation (SHG), an important nonlinear optical phenomenon with diverse applications.…
