Ti³⁺ self-doping in BaTiO₃ ceramic for multi-sensor applications: reduced bandgap with maintained ferroelectric properties

Abstract

Ti3+ self-doped BaTiO3 has been successfully developed as a multifunctional sensor, demonstrating outstanding performance in detecting light intensity, force, and temperature.

Highly stable photovoltaic effects in A2+–Zr4+ (A = Ca, Sr, Ba) co-doped BiFeO3 films with self-polarization

“…Ferroelectric photovoltaic (FE-PV) effects depend on the built-in electric eld resulting from the polarization of ferroelectrics. [1][2][3][4][5] Ferroelectric materials have remarkable capacity to generate charge separation upon illumination aer polarization, leading to an FE-PV effect without the band-gap limitation on open circuit voltage. [6][7][8][9] The potential applications of FE-PV effect in photoelectric conversion, photoelectric detection and other devices have attracted wide interest of researchers.…”
