Such devices have demonstrated better quality factors than acoustic resonators in the 7 GHz range and above. However, the coupling coefficients of these resonators have been limited to less than 3%, primarily due to the restricted design space that is a result of microfabrication challenges related to the patterning of gadolinium gallium garnet (GGG), the substrate material used for growing single-crystal YIG. Here we report magnetostatic wave resonators created through the anisotropic etching of GGG substrates. Our approach, which is based on the YIG-on-GGG platform, uses a transducer with a hairclip-like structure. It is created by developing a microfabrication methodology that involves thinning and deep etching (up to 100 μm) of the GGG substrate. The resulting magnetostatic wave resonators exhibit a coupling of more than 8% in the 6–20 GHz frequency range. A microfabrication methodology that involves thinning and deep etching of gadolinium gallium garnet substrates can be used to create magnetostatic wave resonators that exhibit a coupling of more than 8% in the 6–20 GHz frequency range.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"8 3","pages":"267-275"},"PeriodicalIF":33.7,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41928-025-01345-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the scalable assembly of vertical heterostructures typically requires the use of various chemical solvents for photolithography and subsequent transfer, which can leave behind chemical residues and limit the patterning resolution. We show that patterned van der Waals heterostructures can be fabricated from electrochemically exfoliated 2D flakes using a photoreactive crosslinker. When a 2D van der Waals percolated network with the crosslinker is exposed to ultraviolet light, the network junctions form covalent bonds, thereby enabling improved charge transport and orthogonal patterning of vertically stacked van der Waals thin-film networks without affecting the underlying prepatterned layers. Our approach can be used to create wafer-scale arrays of photopatterned field-effect transistors based on different 2D materials. The field-effect transistors exhibit high spatial uniformity and can be used to create logic gates, namely NOT, NAND and NOR gates. A photoreactive crosslinker can be used to directly pattern thin films of exfoliated two-dimensional flakes, and the technique can be performed sequentially to create patterned van der Waals heterostructures at wafer scales.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"8 3","pages":"235-243"},"PeriodicalIF":33.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477379","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}

Our approach features a hardware-efficient one-step memristor decoding strategy that allows the interface to achieve software-equivalent decoding performance. Furthermore, we show that the system can be used for the real-time control of a drone in four degrees of freedom. We also develop an interactive update framework that allows the memristor decoder and the changing brain signals to adapt to each other.
