Li-N,Li-2N共掺P型ZnO的第一性原理研究
First-prinicples study of Li-N and Li-2N codoped p-type ZnO
摘要
Abstract
Using the density-functional theory,the electronic structures of pure and Li-N,Li-2N codoped wurtzite ZnO systems are explored. It is find that Li-N and Li-2N codoped wurtzite ZnO systems each cause the Fermi level to cross the top of the valence band and to form shallow acceptor level,which indicates that p-type ZnO system can be obtained by codoping Li and N.Moreover,the carrier concentration is enhanced in the Li-2N codoped system and this structure is more favorable for the formation of p-type ZnO.关键词
