研究目的
Investigating the photovoltaic, photoimpedance, and photocapacitance effects of flexible (111) BiFeO3 films for developing new flexible photoelectronic devices.
研究成果
The flexible mica/SrRuO3/BiFeO3/Au cells exhibit strong photovoltaic, giant photoimpedance, and photocapacitance effects under 405-nm-wavelength light illumination. These properties remain stable even when the device is bent, making it a promising candidate for flexible photoelectronic devices.
研究不足
The study focuses on the effects under specific conditions (405-nm-wavelength light illumination and temperatures up to 238 °C). The long-term stability and scalability of the flexible devices need further investigation.
1：Experimental Design and Method Selection:
The study involved the fabrication of flexible (111) BiFeO3 films on a mica substrate using pulsed laser deposition. The films were characterized for their photovoltaic, photoimpedance, and photocapacitance effects under light illumination.
2：Sample Selection and Data Sources:
The samples were epitaxially grown (111) BiFeO3/SrRuO3 films on a (001) single-crystal mica substrate.
3：List of Experimental Equipment and Materials:
Pulsed laser deposition system, X-ray diffraction (XRD), transmission electron microscopy (TEM), piezoelectric force microscope (PFM), Kelvin Probe Force Microscopy (KPFM).
4：Experimental Procedures and Operational Workflow:
The films were grown at different temperatures to study the effect on polarization. The photovoltaic, photoimpedance, and photocapacitance effects were measured under light illumination at various temperatures and bending conditions.
5：Data Analysis Methods:
The data were analyzed to determine the effects of light illumination and temperature on the photovoltaic, photoimpedance, and photocapacitance properties of the films.
