Resistive Switching of Tetraaniline Films: From Ultrathin Monolayers to Robust Polymeric Blends

Oligomers of aniline and their derivatives have electrical and chemical properties that parallel those of polyaniline, while having the advantage of being available as homogeneous, chemically pure materials. Despite this advantage, little experimental data is available on the electrical transport properties of thin films of oligoanilines compared to polyaniline. Here, we investigate three types of ultrathin films (
