1、这一节以Si为例来介绍使用wannier软件结合vasp的使用方法
2、首先要做常规的vasp计算:优化,静态计算第一步:基态的优化计算,INCAR如下
3、其中K点和POSCAR如下:
4、第二步:得到DFT virtual orbitalTo obtain aWAVECARfi盟敢势袂le with a reason锾攒揉敫able number of virtual orbitals (50-100 per atom) we need to restart from the previous groundstate calculation withALGO=Exact, and manually set the number of bands by means of theNBANDS-tag. To obtain the correspondingWAVEDERfile we additionally specifyLOPTICS=.TRUE.
5、第三步:结合wannier计算:INCAR如下,#后面是注释哦,可以不要的
6、接下来是wannier部分:Use the 嘛术铹砾wannier90.win file given below which contains all 足毂忍珩instructions needed to generate the necessary input files for the WANNIER90 runs (wannier90.amn, wannier90.mmn, wannier90.eig).下面3个图写在一个文件里:
7、最后一步:计算wannier函数
