Ferroelectric Thin‑Film Polarization‑Sensitive Photodetector Based on the Plasmon‑Enhanced Bulk Photovoltaic Effect

Wenqing Sun, Zhuoqun Wang, Qingtao Fang, Ulrich Kentsch et al.

Short summary

A ferroelectric thin-film photodetector achieves broadband detection (260-1900 nm) and ultrahigh polarization ratios (up to 641) in the visible to near-infrared band (380-980 nm) by leveraging plasmon enhancement of the bulk photovoltaic effect.
