论文摘要
对激子 - 二质子体被研究为实现极性晶体管的工作元素的平台。激子 - 二态是腔光子的三向叠加,在光学微腔中嵌入的双层半导体系统中的直接和间接激子。使用偶性扩散方程式的强制扩散方程,我们研究了过渡金属二甲化合物(TMD)异质双层中偶极子的室温动力学。具体来说,我们考虑了摩西$ _2 $ -WS $ _2 $异质结构,其中Y形通道引导Dipolariton传播。我们证明,可以通过在最佳方向上施加驱动电压来重新分布极性信号。我们的发现为设计有效的基于双齿dipolariton的光学晶体管设计开辟了一条途径。
Exciton-dipolaritons are investigated as a platform for realizing working elements of a polaritronic transistor. Exciton-dipolaritons are three-way superposition of cavity photons, direct and indirect excitons in a bilayer semiconducting system embedded in an optical microcavity. Using the forced diffusion equation for dipolaritons, we study the room-temperature dynamics of dipolaritons in a transition metal dichalcogenide (TMD) heterogeneous bilayer. Specifically, we considered a MoSe$_2$-WS$_2$ heterostructure, where a Y-shaped channel guiding the dipolariton propagation is produced. We demonstrate that polaritronic signals can be redistributed in the channels by applying a driving voltage in an optimal direction. Our findings open a route towards the design of an efficient room-temperature dipolariton-based optical transistor.
