Spintronics is a promising alternative to the conventional silicon transistor-based electronics that are gradually approaching their physical limitations. Ultrathin two-dimensional van der Waals (vdW) materials (2D materials) with controllable spin degrees of freedom are recognized as extremely promising spintronic materials in architectures for the post-Moore era. In this Perspective, we review recent progress on spin-dependent transport behaviors (SDTBs) confined at the 2D scale, which are the mainstream paradigms for spintronic devices. We first present the mechanism and the key factors of SDTBs in 2D nonmagnetic materials-based hybrid devices. Then, some chemical modulation strategies for inducing short-range magnetic order and magneto-electric performance into 2D nonmagnetic materials are discussed. Furthermore, we concentrate on introducing intriguing SDTBs in 2D long-range ferromagnetic materials-based vdW devices. Finally, we highlight the current challenges in the study of spin-dependent transport of 2D modified materials and 2D material-based spintronic devices, in the hope of accelerating their applications.

二维固体中的自旋相关输运：从非磁性层到铁磁性范德华结构

自旋电子学是传统硅晶体管电子器件的一种很有前途的替代品，这些电子器件正逐渐接近其物理极限。具有可控自旋自由度的超薄二维范德华 (vdW) 材料（2D 材料）被认为是后摩尔时代建筑中极其有前途的自旋电子材料。在这个视角中，我们回顾了受限于二维尺度的自旋相关输运行为 (SDTB) 的最新进展，这是自旋电子器件的主流范式。我们首先介绍了基于二维非磁性材料的混合器件中 SDTB 的机制和关键因素。然后，讨论了将短程磁序和磁电性能引入二维非磁性材料的一些化学调制策略。此外，我们专注于在基于 2D 远程铁磁材料的 vdW 设备中引入有趣的 SDTB。最后，我们强调了二维改性材料和二维材料自旋电子器件的自旋相关输运研究中的当前挑战，以期加速它们的应用。
