Polarization-sensitive UVA photodetector based on heterojunction of ITO and rare-earth doped bismuth ferrite ceramics

Haidee Mana-ay et al.

Summary: This study reports the ferroelectric polarization-enhanced photoresponse of near UV and UVA light in ferroelectric photovoltaic materials. The (Bi0.93Gd0.07)FeO3 heterostructure showed superior photoresponse compared to (Bi0.93Sm0.07)FeO3 due to its more complex domain structure, smaller bandgap, and stronger orbital hybridization. These results demonstrate the potential use of ferroelectric polarization and domain structure for highly sensitive and self-biased visible-UVA photodetectors.

High performance self-powered photodetector based on ferroelectric (001)-oriented Bi0.9La0.1FeO3 thin film

Guangcheng Wang et al.

Summary: This study achieves excellent photodetection properties in a Bi0.9La0.1FeO3 (BLFO(001)) ferroelectric thin film with (001)-orientation growth. Compared to a thin film with random orientation, the responsivity and detectivity of BLFO(001) can be increased by 5 times and 3 times respectively. The strong domain structure of BLFO(001) thin film enhances depolarization field and decreases the built-in field at the interface, generating a large driving force for the separation of photogenerated carriers.

High-performance self-driven photodetectors based on self-polarized Bi0.9Eu0.1FeO3/Nb-doped SrTiO3 p-n heterojunctions

Maocai Wei et al.

Summary: In this study, self-polarized Bi0.9Eu0.1FeO3 (BEFO)/Nb-doped SrTiO3 (NSTO) p-n heterojunctions with excellent photovoltaic effects were synthesized. Under illumination at 405 nm, the heterojunctions exhibited high short-circuit current, open-circuit voltage, and light intensity, as well as high light-on/off current ratio, responsivity, detectivity, and fast response speed. The devices demonstrated superior performance even at weak incident light intensity, surpassing previously reported self-powered photodetectors based on ferroelectric materials.

A self-powered flexible UV-visible photodetector with high photosensitivity based on BiFeO3/XTiO3 (Sr, Zn, Pb) multilayer films

Ze Li et al.

Summary: In this study, a self-powered flexible UV-visible photodetector was fabricated using BiFeO3/XTiO3 (X = Sr, Zn, Pb) multilayer films. The photodetector showed fast and sensitive detection of UV-visible light, thanks to the UV absorption layer XTiO3, a strong built-in electric field in BiFeO3, and the heterojunction electric field. The photovoltaic effect was observed under UV-visible illumination, and the photocurrent densities exhibited excellent fatigue characteristics. The BiFeO3/ZnTiO3 film achieved good responsivity and detectivity under 365 and 500 nm illumination, respectively. The photodetection performance of the BiFeO3/XTiO3 multilayer films on flexible substrates was also confirmed. This work lays a foundation for the applications of ferroelectric-based self-powered UV-visible photodetectors.

Depolarization electric field and poling voltage-modulated Pb,La(Zr,Ti)O3-based self-powered ultraviolet photodetectors

Ying Zhang et al.

Summary: Traditional self-powered ultraviolet photodetectors have low responsivity and specific detectivity due to ineffective separation of photogenerated electrons and holes, while ferroelectrics with large remnant polarization offer effective separation. By preparing Pb0.93La0.07(Zr1-xTix)(0.9825)O-3 (PLZT) ferroelectric thin films with large remnant polarization, the self-powered ultraviolet photodetectors achieved superior photoelectric response performance, surpassing those of recently reported devices.

A. Kathirvel et al.

Summary: This study reports the performance of a white-light photodetector fabricated using thiourea stabilized bismuth ferrite film as the photoactive layer and carbon as the hole collector. The heterojunction BFO/Carbon helps enhance device performance by aiding in excitons dissociation, resulting in high responsivity and detectivity under self-powered conditions. Additionally, the device exhibits excellent stability, repeatability, and a high ON/OFF ratio.
