在本文中,我们回顾了最近的一些理论研究的SiC纳米结构的电子性质,主要集中在本作者所做的研究。在这篇综述的最后,我们提出了一个关键的研究和解释应用一个著名的DFT + U理论简单的SiC分子。我们首先在这里表明,DFT + U的分子系统的解释不同于周期固体。我们将讨论这种方法应用于有限共价体系的不足和挑战。
In this paper, we have reviewed some of the recent theoretical studies on the electronic properties of SiC nanostructures, primarily focusing on the studies performed by the present authors. At the end of this review, we have presented a critical study and interpretations of applying a well-known DFT + U theory to simple SiC molecules. We first show here that the interpretation of DFT + U in molecular systems differs from that of the periodic solids. We will discuss the deficiencies and challenges of this method for applications to finite covalent systems.
