點缺陷 電荷范圍
|
|
|
大家好, 最近在做N 缺陷缺陷形成能。電荷范圍是如何確定的呢? Broberg, D., Medasani, B., Zimmermann, N. E. R., Yu, G., Canning, A., Haranczyk, M., Asta, M., and Hautier, G. (2018) PyCDT: A Python toolkit for modeling point defects in semiconductors and insulators. Computer Physics Communications 226, 165-179 Vacancies: Use the formal charge of the species originally located on the vacant site, oxi, to define the charge range: [−oxi,+oxi]. For GaAs, this procedure results in defect charges ranging from −3 to 3 for both VGa and VAs 這篇文獻里討論了一下,里面認為應(yīng)該是[-oxi,+oxi]. 對于N來說,應(yīng)該是[+3, -3] 嗎? 我不太確定。到底該如何確定電荷范圍? |
