Interfacial interaction at hybrid interfaces results in structural and electronic properties different from organic and inorganic components. In this study, x-ray photoelectron spectroscopy analysis carried out on CuO-hexa-peri-hexabenzocoronene (HBC) bilayers shows the appearance of an additional C 1s peak at lower energy due to Cu–C interaction. Spectroscopic ellipsometry investigation shows that interfacial layer ( ∼ 4 nm) has absorption features related to Cu–C bonding, modified HBC valence states, and Cu2+-π electron interaction. The observed resistive switching property of the CuO-HBC layers is considerably different from junction properties of HBC and CuO layers and is directly related to the hybrid interfacial layer.
