My bad! I misunderstood the Chinese terminology! As to dispersion correction, you can always use it for all the materials, see https://pubs.aip.org/aip/jcp/article-abstract/132/15/1 However, it is noted in many cases its effects can be negligible. But when the system has long range interactions, you had better use it! To me, ferroelectrics especially for those with layered structures are such a platform 發(fā)自小木蟲IOS客戶端 |
