Paper Abstract

Sol-gel spin-coating technique was applied to produce tantalum pentoxide thin films. Pseudo-ternary phase diagrams were used to outline the sol-solution stability and the optimal Ta2O5 thin films formation regions of Ta(OC2H5)5-C2H5OH- CH3COOH-H2O system. Forbidden band gap of Ta2O5 thin film was calculated and found to be Eg equals 3.7 ev. Room temperature cyclic voltammetric measurements clearly revealed a protonic conductor behavior for Ta2O5 thin films.
