Reconfigurable nanoionic and photoionic material and device platforms

ABSTRACT

Nanoionic and photoionic reconfigurable oxides and chalcogenide semiconductors are emerging material platforms for field-based, non-volatile control of electrons and photons in nanoscale optoelectronic device architectures. Their potential low-power requirements, athermal switching mechanism and mixed-mode operation, have facilitated the demonstration of a wealth of highly promising application-driven optoelectronic devices over the last decade that address growing global demands requiring low-power, high-speed, and high-density data storage and signal modulation in ultra-compact architectures. This review highlights advancements in such ion-migration-based materials, fundamental mechanisms, device architectures, and their impact on the observed reconfigurable performance with a view to applications in optical and electronic data storage, signal modulation and beyond-classical computing.
