Basic characteristics of fabricated simples. (a) Schematic illustration of a biological synapse and the IGZO-HfO2-based synaptic memristor. (b) AFM morphology of the IGZO surface of a pristine sample. (c) XPS spectra for the devce under various pulse number stimulations. (d) SEM images of IGZO for the pristine sample. (e) SEM images enlarged for 50times. (f) The lateral profile for the pristine sample.
