摘要

通过接触工程合理设计二维金属半导体异质结构对于开发下一代纳米电子器件至关重要。本文采用范德华设计策略探讨了金与MXene Sc2CF2的接触特性。我们的研究结果表明，在所有金/Sc2CF2异质结构中都形成了n型肖特基触点。值得注意的是，这种异质结构在n型和p型肖特基触点之间具有可逆切换，并且可以通过电门控和垂直应变从肖特基触点调谐到欧姆触点。此外，金/Sc2CF2具有较低的隧道电阻率，为2.80 × 10-10 Ω cm2，表明其具有良好的电荷注入效率。这些发现为金基器件的设计和优化提供了有价值的理论指导，如场效应晶体管（fet）和光电探测器。

Rationally Designed Versatile Heterostructures Consisted of Two-Dimensional Goldene and MXene Sc2CF2

The rational design of two-dimensional (2D) metal–semiconductor (M–S) heterostructures through contact engineering is crucial for the development of next-generation nanoelectronic devices. In this Letter, van der Waals design strategies were employed to explore the contact characteristics between goldene and MXene Sc₂CF₂. Our findings reveal that n-type Schottky contacts are formed across all goldene/Sc₂CF₂ heterostructures. Notably, this heterostructure exhibits reversible switching between n- and p-type Schottky contacts and can be tuned from Schottky to ohmic contacts via electric gating and vertical strain. Furthermore, goldene/Sc₂CF₂ exhibits a low tunneling specific resistivity of 2.80 × 10^–10 Ω cm², indicating its excellent charge injection efficiency. These findings offer valuable theoretical guidance for the design and optimization of goldene-based devices, such as field-effect transistors (FETs) and photodetectors.
