Effect of photoinduction in PANi/TiO2 heterogeneous structure on conductance of PANi component

Year: 2025

Type: article

Abstract: that are created outside the heterostructure surface due to the photoinduction. Acting as strong oxidants, the species play the role of extra acceptor-like dopants and donor dedoping agents that modify the oxidation state and then the hole density of the p-type semiconductor PANi. The initial modification causes a sudden drop in PANi conductance at the start. As the exposure is further prolonged, the oxidation degree of the PANi component is further altered; the initial PANi emeraldine salt is gradually inverted to the emeraldine base, resulting in a conversion of its conductance. The combination of two modifications is explained for the mixing responses in the conductance of the PANi component and the U-turn shape of its baseline.
