First principles calculation of doped silienceZhang Zhenglong(Grade 2012, Class 2, Major Physics, School of physics and Telemunication Engineering, Shaanxi University of Technology, Hanzhong 723001, Shaanxi)Tutor: PanFengAbstract: Silience is a single atomic layer of silicon thin structure is similar to the structure of graphene. And is a new kind of twodimensional material. Because graphene has no energy band gap, and the silience is a kind of twodimensional material with energy band gap which can open. In recent years, it has bee a focus of the research on the electronic structure of the preparation of the silience and the study of the electronic structure of the silience, and opening the energy band gap is also the focus of the study of the electronic properties. This paper mainly introduces the first principle of perfect siliencen and the effect of doping on the first principle of silicon was calculated. Calculation of software and image display, Study on the effect of doping ratio on the energy gap and the way to study the energy gap.Key words: First principles, Density Functional Theory, Silience, Energy gap第9頁共9頁
