Indirect excitons in a potential energy landscape created by a perforated electrode

Indirect excitons in a potential energy landscape created by a perforated electrode

We report on the principle and realization of an excitonic device: a ramp that directs the transport of indirect excitons down a potential energy gradient created by a perforated electrode at constant voltage. The device provides an experimental proof of principle for controlling exciton transport with electrode density gradients. We …
