Complementary metal oxide semiconductor (CMOS) technology operating at cryogenic temperatures with ultra-low power consumption is a key component of this advancement. However, classical CMOS technology, designed for room temperature applications, suffers from band-tail effects at cryogenic levels, leading to an increased subthreshold swing and decreased mobility values. In addition, threshold voltages are enlarged. Thus, classical CMOS technology fails to meet the low power requirements when cooled close to zero Kelvin. In this Perspective, we show that steep slope cryogenic devices can be realized by screening the band tails with the use of high-k dielectrics and wrap-gate architectures and/or reducing them through the optimization of the surfaces and interfaces within the transistors. Cryogenic device functionality also strongly benefits from appropriate source/drain engineering employing dopant segregation from silicides. Furthermore, the threshold voltage control can be realized with back-gating, work-function engineering and dipole formation. As a major implication, future research and development towards cryogenic CMOS technology requires a combination of these approaches to enable universal cryogenic computing at the necessary ultra-low power levels. Ultra-low-power cryogenic complementary metal oxide semiconductor (cCMOS) technology is crucial for quantum computers. This Perspective highlights the challenges of the state-of-the-art technology and proposes solutions to mitigate band-tail effects, control the threshold voltage and achieve ultra-low-power cCMOS devices.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"2 4","pages":"277-290"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past decade, commercial displays based on QD photoluminescence have been successfully introduced, such as QD-enhanced liquid crystal displays, QD organic light-emitting diodes and QD light-emitting diodes. Electroluminescence (EL) from nanostructured materials represents one of the ultimate goals for future display technology, owing to its high efficiency and simple device structure. However, the electroluminescent application of these nanomaterials is still in its infancy, primarily owing to the instability of blue devices and immature mass-production technologies. This Review introduces the progress of photoluminescent QDs, with a focus on advancements in EL. We explore improvements in materials and device design to enhance EL stability and to examine critical mass-production technologies, including high-resolution display innovations. Finally, we outline future research direction for enhancing operation stability of deep-blue EL. Nanostructured materials, such as quantum dots, are potential candidates for next-generation displays. This Review highlights the degradation mechanisms of devices and points out the strategies that can be used to improve the stability of electroluminescence.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"2 4","pages":"263-276"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wildfires sparked by power lines tend to be larger and more destructive, as they often occur during high winds, which accelerate the spread of fires. Moreover, efforts to contain wildfires frequently result in power outages, causing considerable economic disruption. In this Review, we examine wildfire risks related to power-line-induced ignitions, infrastructure damage, climate-induced environmental impacts, grid operational risks, real-time grid management risks, vegetation management risks, and financial and funding risks in the context of a changing climate and their interdependence with power grid infrastructures. We then explore the resilience of power grids under wildfire threats, looking at risk analysis, prediction and mitigation strategies. The Review also shares practical insights and experiences in the USA to inform researchers, policymakers and industry professionals. This Review analyses the growing threat of wildfires to power systems, focusing on power-line-induced ignitions, infrastructure damage and climate-induced risks. It explores wildfire models and resilience strategies, and provides a roadmap for enhancing power grid resilience in the face of escalating wildfire challenges.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"2 4","pages":"225-243"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Internet of Bodies offers a transformative solution by integrating wearable, implantable, ingestible and injectable devices in, on and around the body and thus enabling seamless connectivity in biomedical applications. Since the term was first introduced in the mid-1990s, the Internet of Bodies has made notable progress owing to advances in miniaturized electronics, flexible substrates and low-power design. A critical component of this development is the introduction of human body communication (HBC), which uses the human body as a transmission medium. By replacing the radio front-end with simple direct skin interfaces, sensing and communication modules become smaller, lighter, more energy-efficient and accessible. In this Review, we focus on the role of HBC transceivers for next-generation health-care and body-area networks. We discuss the fundamental principles of HBC, including signal propagation, channel modelling and performance trade-offs. Key design challenges such as dynamic channel variations, skin–electrode interfaces, interference, safety regulations and energy efficiency are analysed. Additionally, we explore the circuit design techniques that affect HBC performance and adaptability. Advancements in miniaturized electronics, low-power design and deep-learning-driven transceiver architectures are needed to further unlock the potential of HBC systems, paving the way for their widespread adoption in personalized health-care and secure body-centric communication systems. By exchanging messages using the human body as a communication medium, human body communication offers a mean to design low-power, miniature Internet of bodies nodes. Accurate channel modelling and low-power strategies are key to HBC widespread adoption.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"2 6","pages":"374-389"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
