Abstract SnO2-ZnO is an important branch of transparent conducting oxides, which includes ZnO, Zn2SnO4, SnO2, and a new phase SnO2(ZnO:Sn)n found in 2012. Three types of heterojunctions were fabricated between these four phases: ZnO-SnO2(ZnO:Sn)n，SnO2(ZnO:Sn)n-Zn2SnO4 and Zn2SnO4-SnO2. 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.
