Schematic illustration of an exciton

Caption

The figure shows a schematic illustration of an exciton excited by a light pulse and moving along an atomically-thin layer. The exciton scatters and randomly changes its direction. In addition, a quantum mechanical interference effect can occur with the exciton propagating through a close loop in both directions at the same time.
