Abstract

Two-dimensional molecular crystals serve as excellent van der Waals gate dielectrics due to their low defect density. Here, we report the synthesis of 2D Sb₂O₃ single crystals using a facile micro-spacing sublimation method. By adjusting the micro-spacing distance, the thickness of the resulting crystals can be precisely tuned, achieving a minimum thickness of 3.09 nm. The as-grown crystals exhibit strong in-plane vibrational anisotropy. This work establishes a controllable synthesis route for high-performance van der Waals gate dielectrics towards next-generation electronics.

二维Sb2O3单晶的可控合成及晶格振动各向异性

二维分子晶体由于其低缺陷密度而成为优良的范德华栅极介质。在这里，我们报告了用一种简单的微间距升华方法合成二维Sb2O3单晶。通过调整微间距距离，可以精确地调整所得晶体的厚度，使其最小厚度达到3.09 nm。生长后的晶体表现出很强的面内振动各向异性。本工作为面向下一代电子学的高性能范德华栅极电介质建立了一条可控的合成路线。
