Semi-metals present unique transport properties due to their distinctive band structures and topological properties, leading to an emergence of semi-metal-based electronic applications. Specifically, these properties include intrinsic low density of states at the Fermi level, the linear dispersion electronic structure and the symmetry breaking in the momentum space, which can be harnessed for improved functionality, energy efficiency and form factor in electronic devices. In this Review, we examine the fundamental properties and devices based on semi-metals and their heterojunctions for electronics applications. We then discuss advanced logic, analogue, memory and interconnect technologies enabled by the physical properties of semi-metals and benchmark them against the state-of-the-art technologies. Finally, we outline the remaining challenges and future perspectives of practical applications of semi-metal heterojunction electronics. This Review examines the unique electronic properties of semi-metals and their microelectronics applications, highlighting recent advancements, challenges and future prospects for semi-metal-based technologies in logic, memory, interconnects and high-frequency devices.

2.5D/3D technologies require designers to reduce electrostatic discharge (ESD) protection of the internal I/O interfaces. To avoid over-design of ESD protection, designers require a more fundamental understanding of the ESD events that occur at this level. Here we present insights, practical guidelines and research directions for circuit designers and suppliers of bonding tools.

Sensors are extensively used in the Internet of Things (IoT) applications, enhancing daily convenience but also raising concerns about privacy leakage. To address this, we advocate for protecting data privacy at the moment it is generated by sensors, rather than trying to secure it afterwards.

Improving the performance and efficiency of batteries is key to enabling the broader adoption of electric vehicles and the effective use of intermittent renewable energy sources. However, this enhancement demands a more comprehensive understanding and improved surveillance of the essential mechanisms that control battery functionality over their entire lifespan. Unfortunately, from the moment batteries are sealed until their end of life, they remain a ‘black box’, and our knowledge of the health status of a commercial battery is limited to current (I), voltage (V), temperature (T) and impedance (R) measurements, at the cell or even module level during use, leading to an over-reliance on insufficient data to establish conservative safety margins and a systematic under-utilization of cells and batteries. Although the field of operando characterization is not new, the emergence of techniques capable of tracking commercial battery properties under realistic conditions has unlocked a trove of chemical, thermal and mechanical data that have the potential to revolutionize the development and utilization strategies of both new and used lithium-ion devices. In this Review, we examine the latest advances in non-destructive characterization techniques, including electrical sensors, optical fibres, acoustic transducers, X-ray-based imaging and thermal imaging (infrared camera or calorimetry), and their potential to improve our comprehension of degradation mechanisms, reduce time and cost, and enhance battery performance throughout their three main life stages: during the manufacturing process, during their utilization and, finally, at the end of their life. This Review examines the latest advances in non-destructive operando characterization techniques and their potential to improve our comprehension of degradation mechanisms and enhance battery performance during the manufacturing process, utilization and at the end of life.
