Non-linear ferroelectric tunnel junctions could be used to create low-power in-memory computing systems.

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.

By embedding silver nanoparticles in the electron transport layer, solution-processed quantum-dot-based photodetectors with a high photon-to-electron conversion efficiency of 6.5% and a low turn-on voltage of 2.5 V can be created for use in infrared imaging applications.

Nonlinear ferroelectric tunnel junction memristors can be used to perform linear vector–matrix multiplication operations at ultralow currents.

A parity–time symmetric system based on two coupled acoustic resonators in a lithium niobate platform can achieve non-reciprocal propagation of acoustic waves.

A parity–time symmetric circuit that uses a switch-mode amplifier and current-sensing phase-delay feedback can wirelessly transfer around 10 W of power to a moving device with a nearly constant total efficiency of 92%.

Semiconducting metal oxide gas sensors with a linear response, broad dynamic range and high baseline stability can be created with the help of a dielectric excitation technique.
