Such a hypothetical metal would possess a spectral gap1,2—a ‘hyper-gap’—in its absorption spectrum, separating the intraband and interband absorptions, in which optical losses could vanish. Currently, this property is achievable only within the bandgap of insulators. However, realizing such a hyper-gap metal demands an exotic electronic structure in which the conducting bands have a bandwidth narrower than their energy separations from the remaining electronic states. Here we present such a hyper-gap in a family of organic metals—the Fabre charge-transfer salts3—through first-principles predictions coupled with both electrical and optical measurements. A transparent window, spanning from red to near-infrared wavelengths, is identified in bulk single crystals that remain transmissive over a thickness of 30 µm. The corresponding absorption coefficient is the lowest among known stoichiometric metals, rivalling thin films of transparent conductive oxides. This finding introduces a path, beyond traditional doping strategies in insulators, to combine electronic conduction and optical transparency.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"152 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144153315","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}

We show direct evidence for an in-plane magnetic order competing with the superconducting state motivated by theoretical proposals. We use two complementary electrical transport measurements. First, in statistically significant switching events in the superconducting state of magic-angle twisted trilayer graphene, we observe non-monotonic and hysteretic responses in the switching distributions as a function of temperature and in-plane magnetic field. Additionally, the system behaves like a network of Josephson junctions due to lattice-relaxation-induced moiré inhomogeneity. Second, in normal regions doped slightly away from the superconducting regime, hysteretic and linear positive magnetoresistance with the in-plane magnetic field shows evidence for an in-plane magnetic order. Furthermore, we estimate superfluid stiffness Js ≈ 0.15 K with strong temperature dependence and show a broadened Berezinskii–Kosterlitz–Thouless transition. Our observations may constrain possible intervalley-coherent magnetic orders and the superconductivity arising from its fluctuations.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"97 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144113722","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, argyrodite is electrochemically decomposed above 2.5 V versus Li+/Li on charge, because free S2− ions in the lattice are oxidized to sulfur at a similar potential as Li2S. Here we demonstrate that creating a strong interaction between the Li ions in argyrodite and the sulfur host synergistically suppresses the oxidation of argyrodite by inhibiting the extraction of Li+ in the initial step. A carbon nitride/N-doped graphene host serves as a proof of concept to demonstrate this effect. Additionally, its moderate electron transport enables SSSB operation and constrains electron mobility at the argyrodite interface. Consequently, SSSBs utilizing this host deliver excellent rate capability and stable long-term cycling compared with non-polar carbon materials. An areal capacity of 2 mAh cm−2 was achieved over 230 cycles at room temperature, whereas a high capacity of 11.3 mAh cm−2 was obtained with 90% retention at 60 °C. The descriptors presented here could enrich the understanding of solid electrolyte redox activities and guide interface and materials design in SSSBs.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"199 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097305","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}

Despite immense efforts to scale down ferroelectric features, however, only few materials have been shown to exhibit ferroelectricity at the unit-cell level. Here we report a controllable unit-cell-scale domain in brownmillerite oxides consisting of alternating octahedral/tetrahedral layers. By combining atomic-scale imaging and in situ transmission electron microscopy, we directly probed sub-unit-cell-segmented ferroelectricity and investigated their switching characteristics. First-principles calculations confirm that the phonon modes related to oxygen octahedra are decoupled from those of the oxygen tetrahedra in brownmillerite oxides, and such localized oxygen tetrahedral phonons stabilize the sub-unit-cell-segmented ferroelectric domain. The unit-cell-wide ferroelectricity observed in our study could provide opportunities to design high-density memory devices using phonon decoupling.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"2 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097306","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}
