Abstract

Charged excitons, or ${X}^{\ifmmode\pm\else\textpm\fi{}}$ trions, in monolayer transition-metal dichalcogenides have binding energies of several tens of meV. Together with the neutral exciton ${X}^{0}$ they dominate the emission spectrum at low and elevated temperatures. We use charge-tunable device...
