轻液体在石墨烯上的失稳脱湿
Spinodal de-wetting of light liquids on graphene
摘要：
我们从理论上证明了由轻原子液体（氢，氦和氮）沉积在悬浮的石墨烯上制成的异质结构中失稳去湿的可能性。扩展我们的二维材料上的薄膜生长理论，包括通过流体力学Cahn-Hilliard型方程的表面不稳定性分析，我们详细描述了所产生的旋节线去湿图案。线性稳定性分析和先进的计算处理的表面流体动力学显示微米级的（通常是材料和原子依赖）模式的“干”的地区。石墨烯上这种不稳定性发展的物理原因可以追溯到原子薄材料和液体中原子之间固有的弱范德华相互作用。类似的现象发生在掺杂的石墨烯和其他二维材料中，例如单层二硫属化物。因此，二维材料代表了一个普遍的理论和技术平台，研究亚稳去湿。
英文摘要：
We demonstrate theoretically the possibility of spinodal de-wetting in heterostructures made of light--atom liquids (hydrogen, helium, and nitrogen) deposited on suspended graphene. Extending our theory of film growth on two-dimensional materials to include analysis of surface instabilities via the hydrodynamic Cahn--Hilliard-type equation, we characterize in detail the resulting spinodal de-wetting patterns. Both linear stability analysis and advanced computational treatment of the surface hydrodynamics show micron-sized (generally material and atom dependent) patterns of "dry" regions. The physical reason for the development of such instabilities on graphene can be traced back to the inherently weak van der Waals interactions between atomically thin materials and atoms in the liquid. Similar phenomena occur in doped graphene and other two-dimensional materials, such as monolayer dichalcogenides. Thus two-dimensional materials represent a universal theoretical and technological platform for studies of spinodal de-wetting.
