Summary: BFMO thin films were successfully deposited on FTO/glass substrates via sol-gel technique, with Mn doping showing significant enhancement in properties compared to pure BFO samples. The Mn doping-induced changes in structure, grain size reduction, and oxygen vacancies were identified as underlying mechanisms for the improved performance of BFMO films, making them promising for ferroelectric photovoltaic device applications.

Summary: In this article, a new all-in-one logic gate system utilizing the photoresponsivity of a self-powered multifunctional BiFeO3 (BFO) sensor material is reported. The BFO sensor can detect light intensity and temperature and execute three common logic gates of AND, OR, and NOT by converting optical and thermal inputs into electrical output. A 3 x 3 logic gate sensor matrix is developed to demonstrate the potential of the BFO logic gate sensor array. This work provides a new route for constructing highly integrated multifunctional electronic devices for large sensing, communication, and computing operations.

Summary: In this study, the crystalline structure, ferroelectricity, leakage current density, magnetic, and nanomechanical properties of BiFeO3 (BFO) films with Ce substitution were investigated. The results showed that Ce substitution improved the ferroelectric and magnetic properties of BCFO films, with an increase in remanent polarization and enhanced saturation magnetization. The BCFO films also exhibited strong anti-fatigue properties and enhanced nanomechanical characteristics influenced by grain size and phase composition.

Summary: This study focuses on the effect of polar order on the optical and photovoltaic properties of ferroelectric materials, using BiFeO3 as the model system. By inducing polarization rotation through A-site La substitution, the optical anisotropy of the samples is continuously reduced, leading to a decrease in the angular dependence of the ferroelectric photovoltaic effect on light polarization. This highlights the inner connection between ferroelectric polarization and optical anisotropy through lattice degree of freedom.

Summary: This study investigated the phase constitutions, ferroelectric, magnetic, and nanomechanical characteristics of BiFeO3 films with Dy substitution. The results showed that the BDFO films exhibited desired ferroelectric and ferromagnetic properties, and the hardness of the films was controlled mainly by the impeded propagation of dislocation by grain boundary. The findings suggest that the radius and magnetic moment of the Dy3+ ions play a critical role in the structural evolution and enhanced properties of the BDFO films.

Summary: This study focuses on quantifying the impact of microstructure on the functionality of titanium dioxide films caused by minor changes in the fabrication process. Thin titanium dioxide films are deposited using sputtering with variations in target composition and working environment. Various characterization techniques are employed to quantitatively analyze the phase, chemical constitution, composition, thickness, roughness, density, etc. of the films and their link to electronic structure, electrical, optical, and surface characteristics. The insights from this study can guide the experimental design for fabricating films with desired functionalities by considering the tolerance range.

Summary: This study reports the multifunctional properties of lead-free BiFeO3-La (BFO-La) thin films, with a focus on the effects of lanthanum doping on structural and optical properties. Lanthanum doping was found to significantly affect defect concentrations, crystallinity, and optical absorption properties of the thin films. The Bi1-xLaxFeO3 (x = 0-20) compositions showed lower direct bandgap values and are considered potential candidate materials for high-performance photovoltaic devices.

Summary: Thin films of BiFeO3 (BFO) were prepared on thin glass and aluminum substrates using spin-coating technique. The structural, optical, and chemical properties of the films were investigated using XRD, Raman, PL, and XPS techniques. The results showed that the BFO film on the glass substrate had a crystalline structure, while the one on the aluminum substrate was amorphous. The films exhibited good density and were free of cracks, but the BFO/glass film showed some porosity. The optical response and chemical analysis suggested the presence of oxygen vacancies in both samples. The theoretical calculations using DFT were consistent with the experimental observations.
