The possibility of ferroelectricity in orthorhombic V2O5 thin flms was investigated. Films were deposited via either a chemical solution deposition (CSD) route or by RF magnetron sputtering. Highly (001) oriented V2O5 flms were achieved with both deposition routes at temperatures as low as 300°C. No evidence for ferroelectricity was observed, even in flms which had been doped to provide local nuclei for polarization reversal. Loss originated from mid-gap trap states stemming from oxygen vacancies that were observed with photoluminescence, supplemented by piezoresponse force microscopy measurements. Furthermore, these trap states may have helped mimic ferroelectricity in previous reports on V2O5.
