Abstract
This talk covers thin-film devices based on amorphous oxide semiconductors (AOS) while discussing related physical mechanisms and potential applications, such as neuromorphic systems. Intentionally using a light-induced metastability mechanism of oxygen defects in AOSs, it is allowed to detect even visible lights, eluding to a persistent photoconductivity (PPC) as an optical memory action. So, this PPC phenomenon is naturally useful for AOS-based optical memory applications, e.g. optical synaptic transistors along with an electrical controllability of a recovery speed with gate pulse or bias. In this respect, AOSs can be promising materials for a low-cost transparent neuromorphic application.
