对“III-V氮化物半导体的准粒子自洽GW理论:能带、带隙弯曲和有效质量”一文的评论

Comments on "Quasiparticle self-consistent GW theory of III-V nitride semiconductors: Bands, Gap bowing, and effective masses"

Diola Bagayoko, Lashounda Franklin, G. L. Zhao

摘要:

对局域密度近似(LDA)计算的几个先前结果的忽略似乎导致了对密度泛函理论(DFT)正确描述纤锌矿GAN(w-GaN)和InN(w-InN)的电子性质的能力的不完整的并且因此误导的表征[Phys.Rev.B82,115102(2010)]。这些评论的目的是提出一个不同的图片的DFT计算,解决自洽的DFT方程组的系统的上述能力。他们还强调,根据实验建立的Burstein-Moss效应,在引用w-InN的带隙时需要指定载流子密度。

英文摘要:

An oversight of several previous results from local density approximation (LDA) calculations appear to have led to an incomplete, and hence misleading, characterization of the capability of density functional theory (DFT) to describe correctly the electronic properties of wurtzite GaN (w-GaN) and InN (w-InN) [Phys. Rev. B 82, 115102 (2010)]. These comments are aimed at presenting a different picture of the above capability for DFT calculations that solve self-consistently the system of equations of DFT. They also underscore, in light of the experimentally established Burstein-Moss effect, the need to specify the carrier density when citing a band gap for w-InN.
