Fcc hcp top 和 bridge这四个位点
Web桥位（bridge）是两个原子中间的位点，类似于A与B之间位点。. 中空位（hollow位）是原子之间的空位。. 如下图C就是处于hollow位上。. 这里要说明一下hollow位有两种，一种 … WebVASP_基础教程 (24)_吸附位点(fcc,hcp,top,bri)对吸附能的影响_Cu原胞吸附O_1是VASP_基础教程 (币留给更需要的人吧，小伙伴们给我点个赞就行，在参加B站的学霸计划，点赞鼓励我做下去）的第24集视频，该合集共计29集，视频收藏或关注UP主，及时了解更多相关视频内容。

WebPacking Density. When the lattice points are inflated gradually, at some point they start to touch each other along the diagonals of the faces of the cube. One can now interpret them as close packed spheres with a radius defined geometrically by 4r = √2a 4 r = 2 a ⇔ r = √2 4 a ⇔ r = 2 4 a. The packing density ϱ ϱ is the ratio of the ...

Obviously, there are six three-fold hollow sites around a Mg ...
WebNov 6, 2015 · 不一样，虽然二者都是密排的点阵型，但是密排面的排列有很大区别，如下图：. FCC的滑移系统比HCP多很多，会显著影响材料的性能。. 例如，FCC的金属（铝等）通常比HCP的（镁等）要延展性好，容易加工得多。. 说它们本质一样实在是无稽之谈。. ps 图 …
