A series of our characterization work demonstrates that the morphology of Bi₂Te₃/MnTe bilayer film mainly depends on the magnetic substrate's growth mode and thickness. We propose that the temperature-dependent quantum interference of the electron wave function caused by disorder drives the transition from weak antilocalization (WAL) to weak localization (WL). Due to spin regulation, WL under low fields originates from the ferromagnetism in MnTe. The quantum interference effect (QIE) model analysis gives the degree of impurity scattering of the electron wave function. The electron wave is scattered by impurities, which causes the Berry phase to change from π to 0, producing a complete WL behavior. The stacked structure provides tunable degrees of freedom, allowing for independent optimization of topological properties and magnetic order through preferential growth orientation of topological insulator (TI) and magnetic layers, respectively.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 8","pages":"5643 - 5655"},"PeriodicalIF":11.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166205","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}

The result shows that the sensor based on the NiZn–Co₃O₄ HCSS displays the highest sensing response of 42.5 at a working temperature of 180 °C. In particular, the NiZn–Co₃O₄ HCSS device possesses a fast response-recovery speed, excellent anti-humidity and outstanding long-term stability of up to 40 days to TEA gas. The improved TEA gas sensing property can be attributed to the intriguing hierarchical core–shell architecture and abundant oxygen vacancy induced by NiZn co-doping.

The identification of NTE materials is crucial for thermal expansion control engineering. Most NTE materials exhibit NTE only within a narrow temperature range, restricting their applications. Achieving NTE across a broad temperature range remains a significant challenge. This study developed a novel PbTiO₃-based system, (1-<i>x</i>)PbTiO₃–<i>x</i>BiLuO₃, incorporating rare-earth elements, using a distinctive high-pressure and high-temperature synthesis technique. We achieved NTE across a broad temperature range by coupling lattice (<i>c</i>/<i>a</i>) with ferroelectric order parameters. The incorporation of BiLuO₃ resulted in distinctive ferroelectric characteristics, including increased tetragonality, spontaneous polarization, and NTE over a broad temperature range. NTE over an extended temperature range has been achieved in 0.95PbTiO₃–0.05BiLuO₃ (<span>(overline{alpha }_{{text{V}}})</span> = −1.7 × 10^–5 K⁻¹, 300–840 K) and 0.90PbTiO₃–0.10BiLuO₃ (<span>(overline{alpha }_{{text{V}}})</span> = −1.4 × 10^–5 K⁻¹, 300–860 K), compared to pristine PbTiO₃ (<span>(overline{alpha }_{{text{V}}})</span> = −1.99 × 10^–5 K⁻¹, 300–763 K). The improved tetragonalities and broader NTE temperature range result from the strong hybridization of Pb/Bi–O and Ti/Lu–O atoms, as demonstrated by combined experimental and theoretical analyses, including high-energy synchrotron X-ray diffraction, Raman spectroscopy, and density functional theory calculations. This study introduces a novel example of NTE over a broad temperature range, highlighting its potential as a high-performance thermal expansion compensator.

Not only that, the heteroatom doping strategy is also bothered with high diffusion barriers toward Na⁺/K⁺. Herein, based on a rationally selected low-cost precursor (sodium alginate–melamine–NaCl), a new HC with high-level N, O heteroatom dopants (21.4 at%) and well-regulated porous structure has been constructed via acylating and controllable pore engineering. Experimental proof and theoretical calculations have been conducted to clarify the influence of heteroatom dopants and porous structures on the ion storage behavior of the designed HC. The rich N, O co-doping could enable efficient Na⁺/K⁺ adsorption and enhanced electron transfer behavior.

Particularly, the optimized N, O dual-doped hierarchical porous HC (NO-HPHC-1, 0.285 mol L⁻¹ NaCl in precursor) with abundant defects from macropores and moderate micropores make it exhibit excellent Na⁺ storage: 127 mAh g⁻¹ at 0.5 A g⁻¹ even after 2000 cycles.
