An impedance measurement technique based on dielectric excitation in oxide semiconductors can provide a highly linear sensing signal over a wide range of gas concentrations.
This Review Article examines the development of non-magnetic non-reciprocal electronics with a focus on devices based on temporal modulation, including approaches based on temporal modulation of permittivity and conductivity, as well as superconducting components for applications in quantum computing.
Metal–semiconductor junctions formed between a transition metal ditelluride and monolayer molybdenum disulfide exhibit nearly ideal Schottky–Mott conditions.
This Review Article examines the development of neural interfaces, which can provide a direct, electrical bridge between analogue human nervous systems and digital man-made devices, considering challenges and opportunities created with such technology.
A reconfigurable metasurface based on integrated optoelectronic pixels can be programmed by visible light to implement different electromagnetic functions.
A metal halide perovskite diode can switch between emission and detection modes, offering over 21% external quantum efficiency for light emission and a sub-picowatt limit for light detection.
This Review Article examines the development of spintronic devices for neuromorphic computing, exploring how magnetic tunnel junctions and magnetic textures can act as artificial neurons and synapses, as well as considering the challenges that exist in scaling up current systems.
An inexpensive and compact short-range radar, which is capable of beam steering and operates at 330–500 GHz, can be used to detect heartbeat-induced chest motions through a person’s clothes.
High-resolution doping patterns can be reversibly written in van der Waals heterostructures using a combination of an electron beam and a back-gate voltage.
This Review Article examines the development of physical unclonable functions, which exploit inherent randomness to give a physical entity a unique ‘fingerprint’ or trust anchor, considering the various potential applications of these devices and the security issues that they must confront.
This Perspective provides a vision for sixth generation (6G) communications in which human-centric mobile communications are considered the most important application, and high security, secrecy and privacy are its key features.
