Quadrupolar–dipolar excitonic transition in a tunnel-coupled van der Waals heterotrilayer
Nature Materials, Published online: 19 October 2023; doi:10.1038/s41563-023-01667-1
The authors report the emergence of quadrupolar excitons in WS2/WSe2/WS2 trilayer heterostructures where the electron is layer-hybridized in WS2 layers and the hole localizes in WSe2. Quadrupolar excitons exhibit distinct behaviour under electric fields, enriching exciton–exciton interactions.Nature Materials, Published online: 19 October 2023; doi:10.1038/s41563-023-01667-1The authors report the emergence of quadrupolar excitons in WS2/WSe2/WS2 trilayer heterostructures where the electron is layer-hybridized in WS2 layers and the hole localizes in WSe2.
