AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons

B. Evrard, H. S. Adlong, A. A. Ghita +6

We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe${}_2$\WS${}_2$ moiré heterostructure. An intense red-detuned laser pulse creates a photon…
