Here, the authors investigate the intrinsic ultrafast transport dynamics in mono- and multi-layered MoSe2 by studying suspended crystals that do not suffer from detrimental substrate effects. They identify four sequential transport regimes, including a phase of negative diffusion and slow exciton propagation.
