| 中文摘要 | A direct correlation is observed between the magnitude of the photoconductivity and cooling oxygen pressure in Bi0.9La0.1FeO3 films. With lower oxygen vacancies (V-Os) films cooled in higher oxygen pressure show obviously decrease in leakage current. Higher level of VOs led to higher free carrier concentration and hence is believed to be responsible for the increase in higher photoconductivity. It is evident that BLFO films with higher VOs cooled in lower oxygen pressure and/or light illumination induce a higher carrier injection, n(i) and thus the conductive mechanism is dominated by space-charge-limited conduction.
