Improvement of fatigue resistance on La modified BiFeO3 thin films
The effect of lanthanum (La) addition in BiFeO3 (BFO) thin films deposited on Pt(111)/Ti/SiO2/Si(100) substrates prepared by soft chemical method was explained. Increasing La concentration promotes changes on structure, microstructure and dielectric/ferroelectric response of films. X-ray diffraction...

| Zusammenfassung: | The effect of lanthanum (La) addition in BiFeO3 (BFO) thin films deposited on Pt(111)/Ti/SiO2/Si(100) substrates prepared by soft
chemical method was explained. Increasing La concentration promotes changes on structure, microstructure and dielectric/ferroelectric
response of films. X-ray diffraction reveals that the films are free of preferred orientations and structural distortion. La addition promotes
an increase in dielectric permittivity. The polarization switching and the fatigue behavior of the BFO films were significantly enhanced by
the La concentration. KCI Citation Count: 37 |
