This article introduces a method for generating spin-polarized photocurrent through light radiation on zigzag MoS₂ nanoribbons. In this regard, we investigate local manipulation by exposing edge states to (i) a ferromagnetic, (ii) an antiferromagnetic exchange field, (iii) a parallel and an antiparallel electric field. These local manipulations at the edges with intrinsic spin-orbit interaction could produce a spin-polarized photocurrent and manipulate optical properties. Even at one edge of the nanoribbon, applying the exchange field could induce a fully spin polarization by light irradiation. Efficient quantum efficiency, significant optical spin polarization, and spin-polarized photocurrent make zigzag MoS₂ nanoribbon an effective structure for improving the performance of spin-photovoltaic devices.

本文介绍了一种通过之字形MoS ₂纳米带上的光辐射产生自旋极化光电流的方法。在这方面，我们通过将边缘状态暴露于（i）铁磁，（ii）反铁磁交换场，（iii）平行和反平行电场来研究局部操纵。具有固有的自旋-轨道相互作用的边缘处的这些局部操纵可产生自旋极化的光电流并操纵光学性质。即使在纳米带的一个边缘处，施加交换场也可以通过光照射引起完全自旋极化。曲折MoS ₂具有高效的量子效率，显着的光学自旋极化和自旋极化光电流 纳米带是一种用于改善自旋光伏器件性能的有效结构。
