Abstract: In heating process, the two obvious resistance mutations were observed for V(2)O(5)films at 320 degrees C and 345 degrees C. The crystallization mechanism of one-dimensional growth was the main reason for the rapid phase transition. Accompanied with the phase change, the microcrystalline and polycrystalline phases formed one after another. The element scan of micro-distribution indicated that the distribution of V and O elements were uniform. A good adhesive force was demonstrated by the scratch test. The multi-level storage was achieved in V2O5-based phase change memory device with a fast speed of 100 ns.
