The approach can, in particular, leverage the concept of inverse design, which involves defining a desired functionality and then using a feedback-loop algorithm to optimize device design. Here we report a simulation-free inverse-design device that can implement various radiofrequency components and can process data in the gigahertz range. The device consists of a square array of independent direct current loops on top of a yttrium iron garnet film that generate a complex reconfigurable magnetic medium. We use two feedback-loop algorithms—direct search optimization and a genetic algorithm—to configure the field patterns and create a linear radiofrequency notch filter and a demultiplexer. A device that consists of a square array of independent direct current loops on top of a film of yttrium iron garnet can generate a complex reconfigurable magnetic medium and be used to solve inverse-design problems experimentally without the use of numerical simulations.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"8 2","pages":"106-115"},"PeriodicalIF":33.7,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056659","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, increasing the pixel resolution can lead to higher electrical pixel crosstalk, primarily due to a shared hole transport layer. Here we show that a silicone-integrated small-molecule hole transport layer can be patterned at the wafer scale with microlithography to mitigate electrical pixel crosstalk. This provides high-density pixelation and improved performance of the hole transport layer itself. With this approach, we create high-fidelity micro-pattern arrays with a resolution of up to 10,062 pixels per inch on a six-inch wafer. The silicone-integrated small-molecule hole transport layer can effectively modulate charge balance within the emission layers, improving the luminance characteristics of organic light-emitting diodes. We also show that organic light-emitting diodes integrated with micro-patterned silicone-integrated small-molecule hole transport layers have a reduced electrical pixel crosstalk compared with organic light-emitting diodes with a typical hole transport layer. The robustness of small-molecule organic films can be increased by incorporating silicone blocks, allowing them to be patterned at high resolution, and used to make pixelated hole transport layers that reduce crosstalk in high-pixel-density displays.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"8 1","pages":"66-74"},"PeriodicalIF":33.7,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044082","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, complex regression tasks that require precise floating-point (FP) computing remain challenging with such hardware, and previous approaches have, thus, typically focused on classification tasks requiring low data precision and a limited dynamic range. Here we describe an analogue–digital unified compute-in-memory architecture for general neural network inference. The approach is based on a low-cost dual-domain FP processor and merges analogue compute-in-memory arrays with digital cores. It exhibits a 39.2 times higher energy efficiency than common FP-32 multipliers during FP neural network inference. We use this architecture to develop a memristor-based computing system and illustrate its capabilities with a fully hardware-implemented complex regression task using YOLO. The system exhibits a 2.7 times higher mean average precision (increasing from 0.27 to 0.724, mAP-50) compared with pure analogue compute-in-memory systems. An analogue–digital unified compute-in-memory architecture can offer native support for floating-point-based complex regression tasks, providing improved accuracy and energy efficiency compared with pure analogue compute-in-memory systems.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"8 3","pages":"276-287"},"PeriodicalIF":33.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026553","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}
