| Abstract: | In the present paper, the main object is the study of producing iron acid bismuth thin film which uses the method of sol-gel with doping neodymium and manganese. Additionally, surface struc- ture and ferroelectric performance are also measured and analysed. The doping type on the film the in- fluence of phase structure and to reduce the BiFeO3 leakage current density of the film is up by four or- ders of magnitude, at the same time it improves the performance of iron. |
