我试着用C代码制作FCC 100和FCC 111晶格。
我已经配置了FCC 100点阵,我做得很好。然而,当我尝试制作FCC 111晶格时,它看起来与我预期的不同。
我使用参考FCC 111晶格(由另一个GUI程序“Amsterdam Density Functional”构建)来比较我的fcc111晶格(使用C代码)。
我的问题是,
我在代码中用来生成FCC(111)的参数是正确的吗?如果他们不正确,请帮助我建立FCC 111晶格。提前谢谢

最佳答案

如果有人能看一下用于制作具有矩形横截面的FCC(111)晶格的C代码,并建议在该代码中可以修改哪些内容,以便制作具有菱形横截面的FCC(111)晶格,这将非常有用,与本问题中提供的GUI-REF相同。
