X射线吸收谱测算锂氮共掺杂氧化锌薄膜局域电子结构
Local Electronic Structure of Lithium Nitrogen Codoped ZnO Films Revealed by X-ray Absorption Fine Structure Spectroscopy
摘要
Abstract
It is to reveal the formation mechanism of Li and N codoped p-ZnO films and the cause for the stable p-type conductivity. The films has been studied by investigating their local electronic structures using X-ray photoelec-tron spectroscopy and X-ray absorption fine structure spectroscopy based on synchrotron radiation source. The signals of Li—N bond and Li—N complex acceptors in the p-ZnO films have been collected, and the acceptor level estimated from photoluminescence spectroscopy is about 122 meV. The formation of Li—N complex acceptors has been con-firmed, and the realization of Li—N bond has been attributed to the origin of the good stability of the p-type ZnO films obtained by Li, N codoping method.关键词
