Abstract

Thin films of crystalline and amorphous V2O3 were deposited by pulsed laser deposition (PLD) and the chemical diffusion coefficients, D, were measured by the potentiostatic intermittent titration technique (PITT). In crystalline V2O3 films, the maximum and minimum D were found to be 1.7 × 10^-12 cm²/s and 5.8 × 10^-15 cmVs respectively, with a general trend for D to rise in single-phase regions. The changes in D correlated well to the known phases in Li_xV₂O₅. In amorphous V₂O₅ films, D exhibited a smooth, continuous decrease as the Li concentration increased.
