However, current techniques for depositing ultrathin metal oxide layers on two-dimensional semiconductors suffer from quality issues that can compromise transistor performance. Here, we show that an ultrathin and uniform native oxide of gallium (Ga<sub>2</sub>O<sub>3</sub>) that naturally forms on the surface of liquid metals in an ambient environment can be prepared on the surface of molybdenum disulfide (MoS<sub>2</sub>) by squeeze-printing and surface-tension-driven methods. The Ga<sub>2</sub>O<sub>3</sub> layer possesses a high dielectric constant of around 30 and equivalent oxide thickness of around 0.4 nm.

A headset technology that can create a sound bubble in which all speakers within the bubble are audible but speakers and noise outside the bubble are suppressed could augment human hearing. However, developing such technology is challenging. Here, we report an intelligent headset system capable of creating sound bubbles. The system is based on real-time neural networks that use acoustic data from up to six microphones integrated into noise-cancelling headsets and are run on the device, processing 8 ms audio chunks in 6.36 ms on an embedded central processing unit. Our neural networks can generate sound bubbles with programmable radii between 1 m and 2 m, and with output signals that reduce the intensity of sounds outside the bubble by 49 dB. With previously unseen environments and wearers, our system can focus on up to two speakers within the bubble, with one to two interfering speakers and noise outside the bubble. An intelligent headset system that uses real-time neural networks run on an embedded central processing unit can create sound bubbles that selectively isolate groups of users from outside sounds.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 11","pages":"1047-1058"},"PeriodicalIF":33.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142609957","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}
