Furthermore, we trace how the twist angle precisely controls the ultrafast formation of interlayer excitons and tunes excitonic hybridization in hetero- and homobilayers, respectively.[SDGs]SDG7conference paper10.1109/IRMMW-THz46771.2020.93709842-s2.0-85103160369https://api.elsevier.com/content/abstract/scopus_id/85103160369
