A multimodal X-ray probe station was utilized to simultaneously investigate the crystallization and electronic conductivity changes during the <em>in situ</em> annealing of amorphous SnO₂ thin films under vacuum conditions. Crystallization was initiated at 200 °C, and most of the amorphous phase was converted to the crystalline phase upon annealing to 500 °C. This trend was consistent with the temperature-dependent electrical conductance variation, demonstrating metal-like behavior. Off-specular X-ray diffraction results confirmed the polymorphism of the SnO₂ thin films, i.e., the coexistence of orthorhombic columbite (C–SnO₂) and tetragonal rutile (R–SnO₂) phases and their epitaxial relationship with the sapphire(0001) substrate. In the 35-nm-thick sample, both C–SnO₂ and R–SnO₂ phases were formed epitaxially, while an additional polycrystalline R–SnO₂ phase was observed with increasing film thickness. This indicated that the formation of the metastable C–SnO₂ phase is determined by the strain field induced by the sapphire(0001) substrate. The result also revealed that the volume effect in the absence of interfacial strain favors the formation of a polycrystalline R–SnO₂ phase in the bulk region of amorphous thin films.</div></div>","PeriodicalId":267,"journal":{"name":"Ceramics International","volume":"51 15","pages":"Pages 20475-20481"},"PeriodicalIF":5.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, Y-doped α-SiAlON ceramics with a nominal composition of Y_0.4Si_9.6Al_2.4O_1.2N_14.8 were synthesized by hot pressing.
