Jellium 模型
Web30 set 2024 · 该模型描述了静电、空化和色散对溶质和溶剂相互作用的影响。 它实现了考虑溶剂化对分子在晶体表面吸附及其反应能垒的影响。 溶剂化模型实现的优势在于其具有处理大型周期性系统(如金属和半导体表面)的能力,以及与标准超软赝势(ultrasoft pseudopotential)和投影缀加波(PAW)势函数具有较好的兼容性。 Web1 gen 2010 · Summary. The simple Jellium Model (JM) for a solid, according to which valence electrons are detached from each atom and the resulting ions are replaced by a uniform background, is presented. The valence electrons, being free of force, spread themselves uniformly over the whole volume of the solid.
