Research paperExperimental GrowthExperimental CharacterizationBand StructureCollective charge excitations between moiré-minibands in twisted WSe₂ bilayers from resonant inelastic light scatteringNihit Saigal, Lennart Klebl, Hendrik Lambers, Sina Bahmanyar et al.arXiv preprint·2024·10.1038/s41565-023-01356-9·arXiv:2310.14417AbstractLow-temperature resonant inelastic light scattering (RILS) is used to probe collective inter-moiré-band excitations in twisted WSe₂ bilayers. The paper reports twisted and hBN-encapsulated WSe₂ bilayers with twist angles near 3° and 8° plus a natural homobilayer, measures their Raman and photoluminescence response, and compares the observed RILS mode energies with miniband transitions from a continuum model adjusted to ab initio simulations.Read more
