Transport of Indirect Excitons in a Potential Energy Gradient

TL;DR

This paper demonstrates the creation of a potential energy gradient for indirect excitons using a shaped electrode and investigates how exciton transport distance varies with density and temperature.

Contribution

The study introduces a method to generate a potential energy ramp for indirect excitons and analyzes their transport behavior under different conditions.

Findings

Transport distance increases with exciton density.

Transport distance increases with temperature.

Potential energy gradient effectively guides exciton transport.

Abstract

We realized a potential energy gradient - a ramp - for indirect excitons using a shaped electrode at constant voltage. We studied transport of indirect excitons along the ramp and observed that the exciton transport distance increases with increasing density and temperature.
