Abstract
A three-terminal synaptic device includes a substrate; a source electrode and a drain electrode which are provided on the substrate and spaced apart from each other. The three-terminal synaptic device further includes: a channel layer provided on the substrate, the source electrode, and the drain electrode; an ion reservoir layer which stores active ions; a gate electrode provided on the ion reservoir layer; and an ion barrier layer disposed between the ion reservoir layer. In particular, the channel layer controls movement of active ions between the ion reservoir layer and the channel layer. The three-terminal synaptic device inhibits rapid movement of ions.
