Abstract

Wide-bandgap semiconductor aluminum nitride (AlN) has a wide range of applications. Here we designed memristors of Al (100 nm)/AlN (10 nm)/Al (100 nm) structure using plasma-enhanced atomic layer deposition (PEALD) and sputtering, which is compatible with CMOS technology and has the ROFF/RON ratio of 3600 times. The special electrode design allows to exhibit interesting unipolarity, enabling SET and RESET operations through only unidirectional voltage. This research reports a new structure of AlN-based memristors, which also inspires further enriching the applications of wide-bandgap semiconductor AlN.
