Abstract

We studied multiexciton dynamics in monolayer ${\mathrm{WSe}}_{2}$ using nonlinear photoluminescence (PL) spectroscopy and Monte Carlo simulations. We observed strong nonlinear saturation behavior of exciton PL with increasing excitation power density and long-distance exciton diffusion, reaching se...
