我们探索了由碳纳米管/RbAg4I5 薄膜复合纳米结构制成的混合离子电子导体在光场存在下的传输特性。由于库仑相互作用而形成离子电子束缚态 (IEBS)，导致电导显着降低。波长相关和功率相关的动态响应表明，光致 IEBS 解离的影响在可见光区域很明显，在近红外区域可以忽略不计。我们的研究结果使人们更深入地了解离子电子相互作用（IEI）对传输的影响，并有望为设计基于 IEI 的新型光电探测器开辟一条道路。
We explore the transport properties of mixed ionic-electronic conductors made of carbon nanotube/RbAg4I5 film composite nanostructures in the presence of optical fields. The formation of ion-electron bound states (IEBSs) due to Coulomb interactions results in significant conductance decrease. The wavelength-dependent and power-dependent dynamic responses show that the effect of photo-induced dissociation of IEBSs is pronounced in the visible region and negligible in near-infrared region. Our results lead to a deeper understanding of the impact of ion-electron interactions (IEIs) on transport and are expected to open up a way for designing new-type photodetectors based on IEIs.
