Metal-diffusion-induced indium tin oxide (ITO) nanoparticles have been observed at the 2-amino-4,5-dicyanoimidazole (AIDCN)/ITO interface. X-ray photoelectron spectroscopy depth profiles reveal that the indium (In) and tin (Sn) elements of the nanoparticles are diffused from the ITO film into the organic layer. And the bonding states of In and Sn in the nanoparticles are identified to be In 2O 3 and SnO 2, respectively. Furthermore, it is found that the ITO nanoparticles have an influence on the electrical property, causing electrical switching behaviour in the Al/AIDCN/ITO sandwich structure.
