单层Al2O3膜在SiO2表面的第一性原理计算研究
First-principle investigation of Al2 O3 monolayer covered on SiO2
摘要
Abstract
We setuped a slab model of AI2O3/SiO2 to investigate atomic coordination and electronic structure. By first-principle calculation, we compared atomic positions of monolayer A12O3 with normal Al2O3 surface to analyze the variation of atomic positions, bond lengths and bond angles. Moreover, we discussed the electronic structure and chemical bonding of the monolayer Al2 O3.关键词
