Interlayer excitons in a van der Waals heterobilayer drift over >10 μm, reaching drift velocities of ~2.66×10^4 m s^-1, limited mainly by finite device size.
- Why it matters: Charge-neutral excitons could enable lower-loss, energy-efficient electro-optical information processing, but fast long-range transport mechanisms are still needed.
- What they did: The team measured exciton transport and identified excitonic potential ramps in the heterobilayer, tracking drift and propagation across exciton densities and temperatures up to 150 K.
- The result: Rapid long-range drift dilutes the initial exciton population quickly and supports a robust transport regime, enabling concepts like field-effect switches and modulators.
