采用分子动力学模拟方法研究了硅在异质石墨板(GSS)上的非均匀凝固过程。这清楚地表明,硅原子集中在一起,形成了由等间距纳米层组成的分级纳米结构。石墨板在GSS表面附近形成了高度有序的液态硅层。这项研究表明,有序液层应该是固体晶体的早期形式,它决定了随后的形核。两个GSS之间的受限纳米空间有利于凝固,导致层间距减小。GSS使硅原子凝固成hcp晶体,而不是面心立方结构。
Molecular dynamics simulations are performed to examine the heterogeneous solidification of silicon on foreign graphite sheets (GSs). It clearly indicates that silicon atoms are concentrated to form hierarchical nanostructures composed of equidistant nanolayers. Graphite plate induces strong ordered liquid silicon layers near the surfaces of GSs. This study suggests ordered liquid layers should be the early form of the solid crystal, which determine the subsequent nucleation. The confined nanospace between two GSs favors the solidification and results in the decrease in the distance between layers. GSs make silicon atoms solidify into an hcp crystal rather than fcc structure.
