摘　　要：SnO_(2)⁃ZnO是重要的透明半导体氧化物体系,本文综述了从2012年发现的一种SnO_(2)(ZnO∶Sn)n超晶格纳米线新相出发,先后设计制备ZnO⁃SnO_(2)(ZnO∶Sn)n,SnO_(2)(ZnO∶Sn)n⁃Zn_(2)SnO_(4)和Zn_(2)SnO_(4)⁃SnO_(2)三种不同的纳米异质结结构,并运用透射电子显微学方法厘清了各相之间的结构演化和晶体学生长关系,为该体系内各相在未来的表界面设计和实际应用奠定了基础。SnO_(2)⁃ZnO is an important branch of transparent conducting oxides,which includes ZnO,Zn_(2)SnO_(4),SnO_(2),and a new phase SnO_(2)(ZnO∶Sn)n found in 2012.Three types of heterojunctions were fabricated between these four phases:ZnO⁃SnO_(2)(ZnO∶Sn)n,SnO_(2)(ZnO∶Sn)n⁃Zn_(2)SnO_(4) and Zn_(2)SnO_(4)⁃SnO_(2).Transmission electron microscopy,combined with crystal structure modeling,was used to study the microstructural evolution and epitaxial growth relationships within these heterostructures.It was found that the Sn⁃O octahedral layer played a crucial role in the phase transition process between neighboring phases.The results in this work provide valuable insights for the design of new growth strategies and the exploration of properties within this material system.
