Si(001)外延ZnSe薄膜界面原子的结合与成键
Donding of interfaces atoms in epitaxial growth of ZnSe thin films on Si(001) substrate
摘要
Abstract
Based on the first principle calculations, two-dimensional epitaxial growth of ZnSe thin films on Si(001) and nitrogen treated Si(001) was modeled by adding monolayer of Zn/Se atoms to the Si(001) and nitrogen terminated Si(001) surface layer. The bonding energy of absorbing monolayer atoms, charge and bonding properties of the interface atoms were investigated to account for the different adherence of Zn/Se atoms and the amorphous Se accumulation phenomenon during the film growth. And it's concluded that the nitrogen treatment of Si(001) surface plays an advantageous role in two-dimensional growth in ZnSe epitaxy on Si(001), and the nitrogen atoms can be the buffer of different non-polar covalent bonding and polar ionic bonding between Si substrates and the epitaxial growth ZnSe.关键词
