由穿孔电极产生的potential energy景观中的间接激子
Indirect excitons in a potential energy landscape created by a perforated electrode
摘要：
我们报告的原则和实现的激子设备：一个斜坡，直接运输的间接激子下的势能梯度所产生的穿孔电极在恒定电压。该装置提供了一个控制激子传输与电极密度梯度的原理的实验证明。我们观察到，激子输运距离沿斜坡增加激子密度的增加。这种效应解释在排斥激子-激子相互作用的无序屏蔽。
英文摘要：
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 observed that the exciton transport distance along the ramp increases with increasing exciton density. This effect is explained in terms of disorder screening by repulsive exciton-exciton interactions.
