关于castep费米能级和修正的问题，求前辈帮忙..
|
||
|
各位大神，初学castep有几个问题想问下。 1.缺陷形成能中的费米能级，有些文章上面直接是相对于完美晶体的价带顶，有些文章是有了个△V的修正。请问以哪个为主？ 2.我的captep计算单点能，为啥输出文件里没有费米能级的真实数值。（bandStr，Dos等文件都没有找到） 3.如果要算△V，是直接拿有缺陷的晶体的价带顶和完美晶体的价带顶对比修正差值吗？ 4.有啥好的计算△V的文献... 这是bandStr文件里的内容，奉献我所有金币求解答，如果在北京地区我请你喝奶茶  。求帮助Job started on host node54 at Wed Sep 11 11:16:02 2019 +-------------------------------------------------+ | | | CCC AA SSS TTTTT EEEEE PPPP | | C A A S T E P P | | C AAAA SS T EEE PPPP | | C A A S T E P | | CCC A A SSS T EEEEE P | | | +-------------------------------------------------+ | | | Materials Studio CASTEP version 2017 | | Ab Initio Total Energy Program | | | | Authors: | | M.
