Observation of Exciton Redshift–Blueshift Crossover in Monolayer WS₂
We report a rare atom-like interaction between excitons in monolayer WS₂, measured using ultrafast absorption spectroscopy. At increasing excitation density, the exciton resonance energy exhibits a pronounced redshift followed by an anomalous blueshift. Using both material-realistic computation and...
