摘要

近年来，二维金属备受关注。然而，这些金属大多在三个方向上具有相对较强的化学键，因此很难合成二维金属。在本文中，我们通过磁控溅射制备了二维和薄膜铜材料。二维铜和薄膜铜的形成是由于金属和基底的热膨胀系数不同所导致的应变和应力的累积。扫描电镜和原子力显微镜研究表明，独立单层的最小厚度约为 1 纳米，横向尺寸可达几毫米。

2D and thin-film copper synthesized via magnetron sputtering

Two-dimensional metals have gained great attention in recent years. However, most of these metals possess relatively strong chemical bonding in three directions; therefore, it is difficult to synthesize 2D metals. In this paper, we prepared 2D and thin- film copper materials via magnetron sputtering. 2D and thin-film copper are formed due to the accumulation of strain and stress associated with different coefficients of thermal expansion for the metal and substrate. SEM and AFM studies suggest that the minimum thickness of a freestanding single layer is approximately 1 nm, with lateral dimensions up to a few millimeters.
