形成能,彈性常數(shù),聲子色散曲線分別說明晶體的什么穩(wěn)定性 已有1人參與

求助: 最近收到摻雜氮化物文章的審稿意見,其中提到需要計算聲子色散曲線來衡量所設(shè)計的摻雜模型的結(jié)構(gòu)穩(wěn)定性,然而我看到的大部分文章中都是用的形成能、彈性常數(shù)九個分量判據(jù)等說明結(jié)構(gòu)的穩(wěn)定性。那現(xiàn)在問題是化學(xué)穩(wěn)定性,力學(xué)穩(wěn)定性以及動力學(xué)穩(wěn)定是分別是用什么進行判斷?聲子色散曲線能說明什么問題呢? |

你好,這是審稿意見! The stabilities of hypothetical models have not been sufficiently addressed. The elastic moduli can only be used to establish the mechanic stability of a solid phase. A complete analysis of the structural stability has to be carried out using the vibrational analysis through for example the phonon dispersion relations, which is absent in the manuscript. |
