Assessing Memristor behavior of Heterostructures based on Reduced Graphene Oxide: PVA nanocomposite - Interdigitated comb structure Al / Au on Glass substrate

In this paper we are assessing the memristive properties of heterojunctions based on Reduced Graphene Oxide:PVA nanocomposite - interdigitated comb structure Al / Au on Glass substrate. By using simple micro-fabrication technological steps we have obtained an interdigitated comb on glass substrate. Al and Au electrodes were patterned through lift-off. We used 2 ratios for RGO:PVA nanocomposite: one with 0 PVA and the other one’s ratio RGO:PVA is 3:1. These solutions were deposited, left to dry and thermally annealed. Raman Spectroscopy was used to investigate the resulting samples. I-V characteristics corresponding to the sample having 0 PVA have hysteresis, which confirms a memristive response.
