Dark exciton signatures in the infrared transient absorption of MoS$_2$ monolayer
Dark excitons play a central role in the nonequilibrium dynamics of two-dimensional semiconductors, but remain difficult to characterize.
Dark excitons play a central role in the nonequilibrium dynamics of two-dimensional semiconductors, but remain difficult to characterize. In this work we show that transient-absorption experiments, with probe pulses tuned in the exciton-exciton transitions energy range…
