However, accessing the effect is challenging because it requires low temperatures (typically below 50 mK) and low bias currents (typically below 1 µA). Here we report Hall resistance quantization measurements in the quantum anomalous Hall effect regime on a device based on the magnetic topological insulator V-doped (Bi,Sb)2Te3. We show that the relative deviation of the Hall resistance from RK at zero external magnetic field is (4.4 ± 8.7) nΩ Ω−1 when extrapolated to zero measurement current and (8.6 ± 6.7) nΩ Ω−1 when extrapolated to zero longitudinal resistivity (each with combined standard uncertainty, k = 1). This precision and accuracy at the nΩ Ω−1 level (or 10−9 of relative uncertainty) reach the thresholds required for relevant metrological applications and establish a zero external magnetic field quantum standard of resistance, which is necessary for the integration of quantum-based voltage and resistance standards into a single universal quantum electrical reference. Hall resistance quantization measurements in the quantum anomalous Hall effect regime on a device based on the magnetic topological insulator V-doped (Bi,Sb)2Te3 show that the system can provide a zero external magnetic field quantum standard of resistance.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 12","pages":"1111-1116"},"PeriodicalIF":33.7,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763494","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, 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 (Ga2O3) that naturally forms on the surface of liquid metals in an ambient environment can be prepared on the surface of molybdenum disulfide (MoS2) by squeeze-printing and surface-tension-driven methods. The Ga2O3 layer possesses a high dielectric constant of around 30 and equivalent oxide thickness of around 0.4 nm. Due to the good dielectric properties and van der Waals integration, MoS2 transistors with Ga2O3 gate dielectrics exhibit a subthreshold swing down to 60 mV dec−1, an on/off ratio of 108 and a gate leakage down to around 4 × 10−7 A cm−2. Ultrathin films of gallium oxide with a dielectric constant of around 30 can be formed on the surface of molybdenum disulfide using a liquid metal-based approach and used as the gate insulator in transistors.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 12","pages":"1126-1136"},"PeriodicalIF":33.7,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637065","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}
