A new type of electronic gating that requires only very low voltages to work could lead to ultra-low-energy microelectronics. This method, known as redox gating, can be used in applications like semiconductors and emerging quantum materials, says Wei Chen, a chemist at Argonne National Laboratory. The research team also theorized that it could be used in neuromorphic computing, a field that draws inspiration from the human brain's ability to generate high computational power from low voltage.
