Their lateral architecture also enables monolithic integration on cost-effective silicon. However, electric-field crowding, as well as surface and buffer trapping, limit the breakdown voltage, degrade dynamic performance and reduce reliability. Here we report intrinsic polarization superjunctions in III-nitride heterostructures for efficient power electronics. We use the spontaneous and piezoelectric polarization fields to induce matched mobile electrons in a two-dimensional electron gas and mobile holes in a two-dimensional hole gas, forming an intrinsically charge-balanced superjunction without intentional doping. With an ohmic contact to the two-dimensional hole gas, both carrier types can be dynamically depleted during switching, which preserves drift-region charge neutrality, producing a nearly uniform electric field and increasing the breakdown voltage under operating conditions. We use the approach to create gallium-nitride-on-silicon polarization superjunction Schottky barrier diodes with a breakdown voltage exceeding 3.9 kV and a specific ON resistance as low as 4.7 mΩ cm2, as well as polarization superjunction transistors with a breakdown voltage exceeding 3.4 kV. The devices exhibit a near-ideal dynamic ON-resistance degradation of less than 15% up to 3 kV, as well as repeatable, temperature-stable and avalanche-like breakdown.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"41 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their narrow bandwidths and small number of comb lines limit practical implementation. Here we report an on-chip broadband magnonic frequency comb based on multi-tone excitation. The octave-spanning magnonic frequency comb is generated at low power thresholds in a continuous yttrium iron garnet thin film. It is driven by spin-wave modulation instability stemming from four-magnon scattering, a nonlinear process validated by micromagnetic simulations. Our magnonic frequency combs exhibit long decay lengths, reaching up to hundreds of micrometres, and offer broad tunability in both the number of comb lines and their frequency spacing. We demonstrate, in particular, a comb with over 2,100 comb lines and densities of up to 200 lines per kilohertz. We also create a magnonic ruler that uses this finely structured spectra to detect microwave frequencies with high precision.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"74 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148769158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical compute interconnects, which replace electrical links with co-packaged photonic channels, could provide low propagation loss, high bandwidth and superior signal integrity. Here, we examine the development of optical chip-to-chip interconnects and co-packaged optics for high-performance computing and artificial intelligence. We analyse the key domains, including electrical subsystems, electro–optical and opto–electronic conversion interfaces, and optical transmission networks, that determine system-level performance across bandwidth, energy and latency metrics. We also provide a technology roadmap from two-dimensional (2D) co-packaged optics, 2.5D interposer-based integration and 3D heterogeneous stacking, identifying critical challenges in thermal management, manufacturability and standardization that will need to be addressed to establish optical compute interconnects as a foundational communication technology for high-performance computing infrastructure. This Review examines optical chip-to-chip interconnects and co-packaged optics for high-performance computing applications, considering key functional domains, the performance of different integration strategies and the critical challenges to widespread adoption.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"9 8","pages":"853-867"},"PeriodicalIF":42.3,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
