However, their application in CMOS technology will require implementation in three-dimensional (3D) transistors. Here we report a framework for designing scaled 3D transistors using 2D semiconductors. Our approach is based on non-equilibrium Green’s function quantum transport simulations that incorporate the effects of non-ideal Schottky contacts and inclusive capacitance calculations, with material inputs derived from density functional theory simulations. A comparative performance analysis of different 3D transistors (2D and silicon based) and channel thicknesses is carried out for both low-standby-power and high-performance applications. This suggests that trilayer tungsten disulfide is the most promising material, offering an improvement in energy–delay product of over 55% compared with silicon counterparts, potentially extending CMOS scaling down to a few nanometres. We also show that 2D semiconductors could be uniquely engineered to create 2D nanoplate field-effect transistors that offer nearly tenfold improvement in integration density and drive current over both 2D- and silicon-based 3D field-effect transistors with similar footprints. A simulation framework for three-dimensionally structured transistors based on two-dimensional materials shows that they could be used to continue complementary metal–oxide–semiconductor scaling with performance and energy enhancements.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 12","pages":"1147-1157"},"PeriodicalIF":33.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825113","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}

Compared to electronic microwave synthesizers, photonic systems that leverage high spectral purity lasers and optical frequency combs can generate microwaves with exceptionally low phase noise. However, photonic approaches lack frequency tunability and have substantial size, weight and power requirements, which limit wider application. Here we address these shortcomings with a hybrid optoelectronic approach that combines simplified optical frequency division with direct digital synthesis to produce tunable low-phase-noise microwaves across the entire X-band (8–12 GHz). This resulted in phase noise at 10 GHz of −156 dBc Hz−1 at 10 kHz offset and fractional frequency instability of 1 × 10−13 at 0.1 s. Spot-tuning away from 10 GHz by ±500 MHz, ±1 GHz or ±2 GHz yielded phase noise at 10 kHz offset of −150, −146 and −140 dBc Hz−1, respectively. Our synthesizer architecture is compatible with integrated photonic implementations and, thus, could be integrated in a chip-scale package. A synthesizer that combines a fixed low-noise photonic oscillator and a direct digital synthesizer—and is based on components that can all be integrated on chip—can create microwave signals that are tunable with low noise.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"7 12","pages":"1170-1175"},"PeriodicalIF":33.7,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804909","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}
