Hierarchical Relaxation in Large-twist-angle Moire Drives Supermoire Formation
Chuqiao Shi, Giovanny Espitia, Yanxing Li +9
Supermoire lattices in large-angle twisted bilayers have recently been shown to emerge from periodic arrangements of commensurate stacking motifs, yet the microscopic structural me…
(Sub)nanoscale Visualization of Reconstruction-Driven Moiré Exciton Localization and Delocalization
Medha Dandu, Sriram Sankar, Giovanny Espitia +12
Spectral fingerprints in optical absorption and emission have typically been used as a signature of exciton localization in twisted moiré bilayers. However, the mechanism by which…
Topology and compact molecular orbitals in twisted bilayer WSe
Chenyuan Li, Rwik Dutta, Fang Xie +4
Recent observations of superconductivity in twisted bilayer WSe (tWSe) have motivated theoretical proposals for unconventional pairing mechanisms. A central question is whe…
Exciton valley depolarization in monolayer MoS2: non-Markovian quantum dynamics, intervalley scattering, and the breakdown of the Dyakonov-Perel mechanism
Yang-hao Chan, Jonah B. Haber, Mit H. Naik +2
In monolayer transition metal dichalcogenides, exciton valley relaxation is typically attributed to the Dyakonov-Perel (DP) mechanism, where frequent intravalley scattering with ph…
Moiré Phonons and Emergent Exciton-Phonon Coupling in a Moiré Heterobilayer
Can B. Uzundal, Woochang Kim, Zhiyuan Cui +13
Moiré superlattices have emerged as a new platform for engineering electronic and optical properties in van der Waals heterostructures, enabling control over correlated and exciton…
Tunable Interlayer Charge-transfer States in MoSe/WS Moiré Superlattices
Zheyu Lu, Jiahui Nie, Tianle Wang +15
Moiré superlattices formed by transition metal dichalcogenide (TMD) heterobilayers provide a versatile platform for studying strongly correlated electronic, excitonic, and topologi…
Signatures of moiré intralayer biexcitons and exciton-phason coupling in WSe2/WS2 heterostructures
Ranju Dalal, Harsimran Singh, Rwik Dutta +6
Interactions among electronic and lattice degrees-of-freedom are foundational to various phases in condensed-matter physics, yet the dynamic interplay between excitonic and phononi…
