The electrical properties of nanostructured δ-Bi 2 O 3 and doped Bi 2 O 3 thin films are studied using electrochemical impedance spectroscopy. Firstly, it is shown that films presenting the cubic fluorite Bi 2 O 3 phase can be stabilized in a wide t

Bismuth oxide (Bi 2 O 3 ) thin films were deposited using a magnetron sputtering system under different conditions of power (radio frequency) and substrate temperature. The film structural characterization was done using X-ray diffraction, where it w

In this paper, we report the stabilization of the δ-phase of Bi2O3 thin films from room temperature (RT) to 500 °C by the addition of tantalum ions. The δ-Bi2O3 phase is the material presenting the highest ionic conductivity; as bulk it is stable
