摘要

This work reported the development of an ionic diode of high rectification ratio with a simple device structure and a quick fabrication process by utilizing asymmetric polyelectrolyte distribution. Detection of aqueous ions was demonstrated by applying this diode as a pH sensor. Two terminal ionic synaptic devices utilizing a similar structural design were also successfully developed.
