摘要

通过金辅助剥离技术成功合成了单层和少层 CoPS3,随后利用导电原子力显微镜研究了它们的传输特性。在 CoPS3 纳米片中可以观察到整流效应,这是由于金/CoPS3 界面形成了肖特基结,尤其是在由两层或多层薄片组成的配置中。单层和少层样品之间截然不同的传输特性表明,垂直方向上的电荷传输行为与范德华间隙有关。热离子发射模型显示,计算得出的 CoPS3 电子亲和力约为 4.84 eV。所获得的结果丰富了有关超薄 MPX3 传输特性的知识库,有助于进一步探索这些材料的传输行为及其在新型电子器件中的潜在应用。

Unveiling charge transport in monolayer and few-layer CoPS3/metal contact: Insight from C-AFM
Monolayer and few-layer CoPS3 have been successfully synthesized via an Au-assisted exfoliation technique, with their transport properties subsequently investigated by conductive atomic force microscopy. Rectification effects can be observed in CoPS3 nanosheets due to the Schottky junction formation at the Au/CoPS3 interface, especially in configurations comprising two or more layer flakes. The distinct transport properties between monolayer and few-layer samples demonstrate that the charge transport behavior in the vertical direction is associated with the van der Waals gap. The calculated electron affinity for CoPS3 is about 4.84 eV, as revealed by the thermionic emission model. The results obtained contribute to the knowledge base concerning the transport characteristics of ultrathin MPX3, facilitating further exploration of the transport behavior of these materials and their potential applications in novel electronic devices.
