[求助]
文獻(xiàn)中關(guān)于優(yōu)化晶格常數(shù)的這段敘述不明白什么意思,求助大神!!

Geometric relaxations are done by keeping the in-plane lattice parameter ‘a(chǎn)’ fixed and relaxing the out-of-plane lattice parameter ‘c’. Residual force threshold was decreased to 0.5 eV/Å where necessary in order to resolve differences between states close in energy. An external stress has been applied along the c axis in order to compensate for the overestimation of cell volume. 弛豫c軸,肯定是估計(jì)大了,但是說(shuō)在c軸加一個(gè)額外應(yīng)力來(lái)補(bǔ)償是什么意思?加應(yīng)力難道不是改變c軸嗎?還有中間那一句“Residual force threshold was decreased to 0.5 eV/Å where necessary in order to resolve differences between states close in energy.”何解? |
找到一些相關(guān)的精華帖子,希望有用哦~
