| Popis: | This chapter presents exciton transport in a potential energy gradient—a ramp—created by a shaped electrode at constant voltage. We utilize the ability to control exciton energy by electrode shape and design the shape of a top electrode on the sample surface so that a voltage applied to it creates a constant potential energy gradient for indirect excitons in the CQW. The excitonic ramp realizes directed transport of excitons as a diode realizes directed transport of electrons. |
