- Multidimensional coherent spectroscopy (MDCS) on monolayer WS2 reveals Fermi polaron interactions
- Phase-space filling drives new optical selection rules, where excitons compete for the same electron
- Identification of a novel, cooperatively-bound exciton-exciton-electron state
Recent Australian-led research has provided a world’s first measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing complex quantum materials.
Researchers at Swinburne University of Technology found the signatures of interactions between exciton-polarons in experiments on the 2D semiconductor monolayer tungsten-disulfide.
