  • Theory predicts trion signatures in ARPES spectra

    What the study found The study presents a first theoretical analysis of how trions, or charged excitons, may appear in angle-resolved photoemission spectroscopy (ARPES) spectra of monolayer transition-metal dichalcogenides. It reports that the extra charge carrier changes the spectral position and shape compared with neutral excitons, and that mass-imbalanced trions are predicted to show a…
