In this tutorial article, we provide a foundation for the thin-film engineer/scientist conducting their first measurements using XRD. We give a brief introduction of the principle of diffraction and description of the instrument, detailing the relevant operation modes. Next, we introduce five types of measurements essential for thin film characterisation: (2theta /omega) scans, grazing-incidence scans, rocking curves, pole figures, and azimuth scans (or ϕ scans). Practical guidelines for selecting the appropriate optics, mounting and aligning the sample, and selecting scan conditions are given. Finally, we discuss some of the basics of data analysis, and give recommendations on the presentation of data. The aim of this article is to ultimately lower the barrier for researchers to perform meaningful XRD analysis, and, building on this foundation, find the existing literature more accessible, enabling more advanced XRD investigations.\u0000</div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"47 4","pages":"141 - 163"},"PeriodicalIF":1.7,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4848223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phase analysis revealed that up to x = 0.035, Ga3+ and Ta5+ completely dissolve in BNBT perovskite structure and substitute in B-site. Increase in x more than 0.02 resulted in formation of pinched P-E loops accompanied by sharp decrease in Pr. This observation can be attributed to the phase transition from ferroelectric (FE) to a non-polar ergodic relaxor (ER) which could be transformed reversibly to a FE phase by applying an electric field. According to temperature-dependence dielectric constant results, transition temperature from FE to ER phase decreased and for ceramic with x = 0.03 shifted to lower than room temperature with increasing GT content. As a result, enhanced unipolar electric field-induced strain (0.4% under 60 kV/cm) corresponding to d33* of 667 pm/V was obtained in this ceramic.
