However, at the centimetre scale necessary for practical applications, previous multiwavelength achromatic metalenses have faced challenges in mass production and exhibited a low numerical aperture (NA), which limits their practical application in NEDs. Here we introduce a centimetre-scale red, green and blue achromatic metalens fabricated using a roll-to-plate technique and explore its potential for practical applications in NEDs. This metalens is designed through topological inverse design utilizing a finite-difference time-domain simulation for entire areas (~10,000λ). Our design method demonstrates the ability to compensate chromatic aberrations even at the centimetre scale and high NA with low-index materials such as resin suitable for scalable manufacturing. In addition, we developed a compact NED by integrating the metalens with computer-generated holography (CGH). In this NED system, the high-NA metalens address the limitations of narrow field of view and extensive empty space typical of conventional CGH-based NEDs. The CGH optimization model further resolves the challenges of broadband operation and off-axis aberration in centimetre-scale red, green and blue achromatic metalenses. Using a topological inverse design process with finite-difference time-domain simulations, the authors fabricate high-numerical-aperture red, green and blue achromatic metalenses for compact near-eye displays using a scalable roll-to-plate technique.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 4","pages":"535-543"},"PeriodicalIF":37.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477391","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, investigations into their optical activities and related chiro-electronic properties are constrained by experimental challenges, particularly in the precise control over the chirality of these materials. Here a universal wax-aided immersion method is developed to yield graphene rolls with controllable chiral angles, and the method can be generalized in other two-dimensional materials for high-yield fabrication. The left-handed and right-handed rolls exhibit optical activity and excellent spin selectivity effects with a spin polarization over 90% at room temperature. The discovery of tunable chirality-induced spin selectivity in tailored roll-shaped allotropes, achievable only through precise control of chirality, distinguishes itself from other carbon materials or existing chiral materials. Our Dirac fermion model shows that the electrons moving predominately along one side of the chiral roll develop a preferred spin polarization, and the rolling-chirality-induced spin selectivity is a result of this finite spin selectivity effect. Our method opens up opportunities for endowing achiral two-dimensional materials with tunable chirality, and may enable the emergence of quantum behaviours and room-temperature spintronic technologies. A wax-aided immersion methodology is developed to yield graphene rolls with tunable chiral angles; these graphene rolls exhibit promising chiral electronic properties beyond those of other carbon allotropes.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 3","pages":"377-383"},"PeriodicalIF":37.2,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462166","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 the utility and importance of this property in regard to scientific and engineering applications, the atomic-scale location of the force that returns an object to its original shape remains elusive in molecular crystals. Here we use a series of density functional theory calculations to locate precisely where the energy is stored when single crystals of three molecular materials are placed under elastic stress. We show for each material that different intermolecular interactions are responsible for the restoring force under both expansive and compressive strain. These findings provide insight into the elastic behaviour of crystalline materials that is needed for more efficient design of flexible technologies and future smart devices. Elasticity is ubiquitous in everyday life, but the molecular origin of the restoring force remains elusive.

A unique capability emerges when a two-dimensional magnet is also a semiconductor that features tightly bound excitons with large oscillator strengths that fundamentally determine the optical response and are tunable with magnetic fields. Here we report a previously unidentified type of optical excitation—a magnetic surface exciton—enabled by the antiferromagnetic spin correlations that confine excitons to the surface of CrSBr. Magnetic surface excitons exhibit stronger Coulomb attraction, leading to a higher binding energy than excitons confined in bulk layers, and profoundly alter the optical response of few-layer crystals. Distinct magnetic confinement of surface and bulk excitons is established by layer- and temperature-dependent exciton reflection spectroscopy and corroborated by ab initio many-body perturbation theory calculations. By quenching interlayer excitonic interactions, the antiferromagnetic order of CrSBr strictly confines the bound electron–hole pairs within the same layer, regardless of the total number of layers. Our work unveils unique confined excitons in a layered antiferromagnet, highlighting magnetic interactions as a vital approach for nanoscale quantum confinement, from few layers to the bulk limit. The emergence of magnetically confined surface excitons enabled by antiferromagnetic spin correlations is reported, which leads to the confinement of excitons to the surface of layered antiferromagnet CrSBr.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 3","pages":"391-398"},"PeriodicalIF":37.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143443728","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}

In van der Waals layered crystals, enhanced correlations have been tailored in reduced dimensions, enabling excitons with giant binding energies and emergent phases including ferroelectric, ferromagnetic and multiferroic orders. Yet, correlation design has primarily relied on structural engineering. Here we present quantitative experiment–theory proof that excitonic correlations can be switched through magnetic order. By probing internal Rydberg-like transitions of excitons in the magnetic semiconductor CrSBr, we reveal their binding energy and a dramatic anisotropy of their quasi-one-dimensional orbitals manifesting in strong fine-structure splitting. We switch the internal structure from strongly bound, monolayer-localized states to weakly bound, interlayer-delocalized states by pushing the system from antiferromagnetic to paramagnetic phases. Our analysis connects this transition to the exciton’s spin-controlled effective quantum confinement, supported by the exciton’s dynamics. In future applications, excitons or even condensates may be interfaced with spintronics; extrinsically switchable Coulomb correlations could shape phase transitions on demand. The antiferromagnetic-to-paramagnetic phase transition in a two-dimensional semiconducting magnet, CrSBr, induces an exciton confinement transition from a strongly bound quasi-one-dimensional state to a weakly bound interlayer-delocalized state.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 3","pages":"384-390"},"PeriodicalIF":37.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41563-025-02120-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143443729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
