Abstract

Read online

Excitons in 2D semiconductors suffer from a weak response to in-plane electric fields, inhibiting their transport beyond the diffusion length. Here, the authors demonstrate the directional, long-range transport of interlayer excitons in bilayer WSe2 driven by the propagating potential traps induced by surface acoustic waves.
