We theoretically investigate the properties of exciton-polaron moving through a magnetic barrier in monolayers (1Ls) transition metal dichalcogenides (TMDs): MoS₂, WS₂, MoSe₂, and WSe₂. We find that the exciton-polaron has the highest ground state energy in WS₂ and the lowest one in MoSe₂. It is seen that the magnetic barrier stabilizes the excitonic polaron system subjected to thermal perturbation. We demonstrate that the entropy of the system is very sensitive to the type of monolayers TMDs, the length scale of the barrier, the temperature. We observe that the higher the magnetic length, the greater the disorder in exciton-polaron system and the highest entropy is in MoSe₂. Also, the mobility and the lifetime of exciton-polaron decrease with the enhancement of the magnetic length. We observe the highest mobility and lifetime in WS₂. Moreover, We show that the optical absorption appears when the photon energy is more than twice phonon energy and the absorption coefficient is higher when the incident photon induces an in plane field. MoS₂ presents the highest amplitude of optical absorption.

我们从理论上研究了激子极化子在单层 (1Ls) 过渡金属二硫属化物 (TMDs) 中穿过磁势垒的特性：MoS ₂、WS ₂、MoSe ₂和 WSe ₂。我们发现激子极化子在WS ₂中具有最高的基态能量，在MoSe ₂中具有最低的基态能量。可以看出，磁势垒稳定了经受热扰动的激子极化子系统。我们证明了系统的熵对单层 TMD 的类型、势垒的长度尺度、温度非常敏感。我们观察到磁长度越高，激子-极化子系统的无序性越大，最高熵在 MoSe₂ . 此外，激子-极化子的迁移率和寿命随着磁长度的增加而降低。_{我们观察到 WS 2}中最高的迁移率和寿命。此外，我们表明当光子能量是声子能量的两倍以上时会出现光吸收，而当入射光子诱导平面场时，吸收系数会更高。MoS ₂呈现出最高的光吸收幅度。
