Here we demonstrate the electrically programmable symmetry breaking of phonon polaritons via non-Hermitian dissipation engineering. In a heterostructure composed of α-MoO3 and aligned carbon nanotubes (A-CNTs), we identify the A-CNT layer as an anisotropic dissipative medium. Driven by overdamped carrier dynamics, the nanotubes preclude polariton hybridization, exerting a proximity-induced resistive coupling instead. Thus, the A-CNT layer operates as a tunable momentum-space loss filter that selectively attenuates propagation along specific crystallographic directions. By electrostatically gating the A-CNTs to regulate their Drude loss, we achieve the continuous and reversible tuning of the polariton topology with transitions from symmetric hyperbolas to asymmetric shear wavefronts. Unlike refractive-index engineering that requires strict wavevector matching, this dissipative filtering mechanism allows for topology shaping without coherent hybridization, establishing dissipation as a programmable degree of freedom in topological nanophotonics and non-Hermitian device physics.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"12 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899605","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}

Here we report a structurally driven strategy for modulating carrier-selective electronic characteristics through the organic-cation-induced reconfiguration of lead iodide octahedral connectivity. Two closely related imidazoline-based cations, which differ by only a single heteroatom, drive the formation of one-dimensional organic lead triiodide phases with distinct octahedral-sharing patterns. Single-crystal analysis combined with theoretical calculations reveals that the variation in connectivity reshapes orbital coupling, leading to pronounced changes in the work function and absolute band-edge positions that give rise to distinct carrier-selective interfacial behaviour without the introduction of extrinsic dopants. Leveraging this structural reconfiguration-induced electronic modulation, we realize complementary charge-selective contacts in perovskite solar cells, achieving a power conversion efficiency of 27.61% (certified steady-state 27.19%), together with excellent operational stability and scalability, including 22.26% efficiency in 655-cm2 modules.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148888012","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 stronger π-stacking interactions and tighter interlayer packing in (4ClPEA)2SnI4 among (4XPEA)2SnI4 structures (X = H, F, Cl, Br) substantially impede oxygen and water diffusion, enabling superior air and moisture stability and bright photoluminescence lasting several months in ambient air. The addition of 4ClPEA markedly improves 2D/3D THP film crystallinity and orientation, leading to 16.2% efficient 2D/3D THP solar cells that show prolonged storage stability and operational stability at 55 °C surpassing 1,000 h.

Here we demonstrate that moiré twisting can also be harnessed to effectively enhance the tensile plasticity of bulk layered van der Waals crystals. We show that interlayer moiré twisting, spanning a broad range of twist angles commensurate with the crystal's translational symmetry, can be controllably introduced through simple off-axis compression in ternary bulk layered van der Waals crystals. It facilitates efficient stress relaxation under mechanical loading with a further increase in the moiré twist angles and enables a substantial increase by up to 360% in room-temperature macroscopic tensile ductility, reaching 30% tensile strain along the a-b plane. Moreover, moiré twisting occurs only between layers and, thus, negligibly affects the in-plane electronic properties. By establishing tunable moiré twisting as an effective mechanism for plastic deformation, this work provides a broadly applicable strategy for enhancing tensile ductility in bulk layered materials.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148866218","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}

Recently, twisted van der Waals materials have enabled unprecedented phonon polariton propagations, such as canalization. However, nano-optics still presents an important limitation: obtaining polariton propagations on demand. Here we combine deep neural networks with twisted polaritonic multilayers to enable on-demand design of phonon polariton propagation. We demonstrate canalization, bicanalization and tricanalization in twisted α-MoO3 homostructures over previously unexplored frequencies (600-800 cm-1). We illustrate the practical potential of our method by achieving a desired polariton propagation in an existing α-MoO3 bilayer by adding an extra α-MoO3 layer. Finally, we extend our neural networks to a variety of other materials, allowing us to predict canalization from the visible to the terahertz regime. Our deep-learning-based approach offers considerable potential for advancing nanophotonic applications in areas such as sensing or thermal management.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851150","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}
