Synthesis of Bi2Se3 Nanosheets with Applications in Photoelectrochemical Photodetectors

open access: yesSmall, EarlyView.
Hexagonal Bi2Se3 nanosheets are synthesized via a mild hydrothermal route with the assistance of a PVP surfactant. The as‐fabricated Bi2Se3 enables an excellent photoelectrochemical photodetector, which exhibits an apparent response across 334–578 nm. The Bi2Se3‐based devices deliver ultrafast (<70 ms) response and remarkable stability, opening a low ...

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...
