As the temperature increases, the stable second phases transform from Al<sub>6</sub>(Fe,Cu) to Al(Fe,Mn)Si and ultimately to Al<sub>3</sub>Fe. The average sizes of both the second phases and recrystallized grains initially decrease and then increase with the increasing temperature, reaching their minimum sizes at 460°C, which are 1.19 μm and 9.09 μm, respectively. The annealing process influences the tensile strength and elongation of 1235D cold-rolled sheets by affecting the type and size distribution of the second phases, which subsequently affect the recrystallized grain size.

Compared to hafnia (HfO<sub>2</sub>), zirconia (ZrO<sub>2</sub>) thin films have been understudied in spite of significant recent progress. Doping has emerged as a promising tool to tune the ferroelectric properties of HfO<sub>2</sub> and Hf<sub>x</sub>Zr<sub>1-x</sub>O<sub>2</sub> (HZO). However, an extensive study of the effects of doping on the structural and ferroelectric properties of ZrO<sub>2</sub> is still widely missing. In this study, through density functional theory (DFT) and ab initio molecular dynamics (AIMD) calculations we investigate the effects of B, Si, Al, Mg, Sc, Ca, Ce, Ta, Hf, Y, Sr, La, Ba and Rb doping on the structural distortions, relative phase stability, phase transition temperatures, spontaneous polarization and piezoelectric response of the monoclinic (m-), polar orthorhombic (o-) and tetragonal (t-) phases of ZrO<sub>2</sub> at 3.125 and 6.25 cat% doping concentration. We demonstrate that the spontaneous polarization magnitude in ZrO₂ can be significantly enhanced through doping with Si, B, and Al. In addition, our results reveal that the relative phase stability and phase transition temperatures of ZrO₂ can be tuned by doping. Specifically, our calculations confirm that Si doping promotes the stabilization of the t-phase in ZrO₂. Furthermore, we show that doping shifts the phase transition temperature, leading to substantial improvements in piezoelectric response, with up to a sevenfold increase observed in Al-doped ZrO₂. Consequently, this work highlights the most promising dopants capable of enhancing the ferroelectric and piezoelectric properties of ZrO₂ thin films.","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"27 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the practical application is limited by high synthesized temperature and inert atmosphere requirements during conventional hot-injection process. In this paper, the synthesis of CsPbX<sub>3</sub> (X = Cl, Br, and I) NCs in non-polar media was developed at room temperature using trimethylsilyl halides as halogen precursors and a ternary ligand system comprising dodecylbenzenesulfonic acid, oleic acid, and oleylamine.

By precisely controlling Cs/Pb ratios, the phase compositions from zero-dimensional Cs<sub>4</sub>PbX<sub>6</sub> NCs to three-dimensional CsPbX<sub>3</sub> NCs were adjusted. CsPbBr<sub>3</sub> NCs created using optimized conditions exhibited outstanding PL properties including high PLQYs (94.4%), narrow full width at half maxima (15 nm) of PL spectra, and remarkable environmental stability (&gt;90 days). Cs/Pb ratios play important role for tunable PL, in which CsPbBr<sub>3</sub> samples revealed bright blue to green emitting while the PL of CsPbI<sub>3</sub> NCs was adjusted from green, yellow to red. These results are ascribed to the interface controlling via ligand growth kinetics. In addition, the CsPbX<sub>3</sub> NCs synthesized by this method can maintain high stability under UV irradiation and water contact conditions, showing the application potential in the field of display. This work establishes a novel strategy for ambient-temperature synthesis of high-quality perovskite NCs with tunable PL performance.","PeriodicalId":18253,"journal":{"name":"Materials Today Physics","volume":"27 1","pages":""},"PeriodicalIF":11.5,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141163","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}

This can be microscopically and macroscopically driven by applying external stimuli such as mechanical stress, electric field, temperature, and chemical modification. For instance, non-zero net dipole moments are formed in a material with the presence of local charged defects or their clusters, which can alter the crystal structure, charge states, and electrostatic potential across the material. Here, a conceptual approach is demonstrated to defects-mediated symmetry breaking that allows for built-in polarization in a nominally centrosymmetric defective oxide, GdxCe1-xO2-δ (CGO) films by creating a macroscopic charge asymmetry. These results show that switchable and enduring polarization in CGO films is governed by the electric field-driven redistribution of oxygen vacancies with a critical field strength of ≈0.5 MV cm-1 at room temperature. This leads to notable and persistent pyroelectric effect with a coefficient of ≈180 µC m-2 K-1. These findings highlight the potential to develop high-performance, sustainable, environmentally friendly polar film materials by manipulating ionic defects from their centrosymmetric ground states. This approach provides new opportunities to expand the range of polar materials in current and future energy and electronic applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"41 1","pages":"e03685"},"PeriodicalIF":29.4,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
