Pre-adsorption of water molecules on a material surface, followed by assembly of a van der Waals (vdW) structure, provides a vdW water gap with a height that can be precisely tuned through variation of the amount of water adsorbed at the interface. This approach is applicable to different two-dimensional and even three-dimensional homo- and heterojunctions.

精确控制范德华间隙

水分子在材料表面上预吸附，然后组装范德华 (vdW) 结构，提供了 vdW 水隙，其高度可以通过改变界面处吸附的水量来精确调节。这种方法适用于不同的二维甚至三维同质和异质结。
