Electric field poling effect on the photosensitivity of samarium-doped bismuth ferrite ceramics

Achieving high microscale photoconductivity in Gd-modified bismuth ferrite via modulating ferroelectric polarization

“…Suitable chemical dopants have been explored to elevate the photovoltaic and photosensing performance in BFO-based materials. [16][17][18][19][20][21][22][23][24] The fundamental processes governing the magnitude of the photocurrent include the excitation of electron-hole pairs via the absorption of incident photons, the movement of photogenerated carriers across the material under the influence of an E field, and the recombination of electrons and holes. 25 Most photodetection studies are conducted at the macroscopic scale, typically with the three-dimensional (3D) heterostructure design wherein the ferroelectric material was sandwiched between top and bottom electrodes.…”
