WebJan 28, 2016 · According to the format for born effective charge file as written in Phonopy manual, I should first start with the unit conversion, then dielectric constant, after that comes Born effective charges (9 columns) for each atom. So I prepared the born charge file following this way. When I employed "--nac born_charge_file_name", phonopy told me the ... Web相关度排序; 发帖时间排序; 37: 1/2: 1: 2: 下一页
born effective charge prediction #172 - Github
WebI have a ABO3-perovskite structure that is substitutionally doped for certain composition. The pure ABO3 structure has no off-diagonal elements in Born effective charge tensor calculated with the ... WebLet us start with the calculation of the static dielectric properties. The most convenient way to determine the Born effective charges, dielectric-, piezoelectric tensors is by means of density functional perturbation theory ( LEPSILON = .TRUE. ). ISMEAR = 0 SIGMA = 0.01 EDIFF = 1.E-8 ## to get the Born effective charges ## and the macroscopic ... greeting card making new year
