长期以来，人们一直在能量传输领域探索偶极相互作用的环境调控。本文研究可调谐石墨烯单层膜对近H型或J型分子聚集体的影响，重点关注一种耦合类型向另一种类型的反转。将石墨烯建模为沉积在金属衬底上，我们发现随着石墨烯表面电导率的变化，耦合反转的参数区域也会发生相应改变。这为在实际系统中观测预测的耦合反转提供了一条途径，即通过在单次实验运行中动态改变表面电导率来实现。
英文摘要
Environmental modification of dipole interactions has long been explored in energy transport. Here we consider the effects of a tunable graphene monolayer upon nearly H-type or J-type molecular aggregates, concentrating on the inversion of one type of coupling to the other. Modelling the graphene as being deposited on a metallic substrate, we find that as the surface conductivity of the graphene is varied, there is a corresponding change in the parameter region over which coupling inversion is predicted. This provides a route towards observing the predicted coupling inversion in a real system by dynamically changing the surface conductivity during a single run of an experiment.
