摘要

本文提出了一种在空间分离的过渡金属二硫族化合物单层上形成的由电子气体和偶极子玻色-爱因斯坦凝聚体组成的杂化系统中的谷霍尔效应理论。通过分析激子玻色-爱因斯坦凝聚的基本激发下电子的斜散射，研究了横向电流对结构空间尺寸以及电子气体的温度和密度的依赖性。

Valley Hall Effect in a Two-Dimensional Electron–Exciton System

A theory of the valley Hall effect in the hybrid system consisting of an electron gas and a Bose–Einstein condensate of dipole excitons formed on the basis of spatially separated monolayers of transition metal dichalcogenides has been proposed. The dependences of the transverse electric current on the spatial dimensions of the structure, as well as on the temperature and density of the electron gas, have been studied by analyzing the skew scattering of electrons on elementary excitations of the exciton Bose–Einstein condensate.
