Polarization‐Sensitive and Self‐Driven Pyro‐Phototronic Photodetectors Based on MoS₂‐Water Heterojunctions (Advanced Optical Materials 11/2024)

Pyro-Phototronic Photodetectors Conventional photodetectors require an external voltage bias which can limit their applications, whereas pyro-phototronic photodetectors can use the combined photovoltaic and pyroelectric effects to detect optical signals at zero bias. In article number 2302651, Michael M. Adachi and co-workers report a high-performance pyro-phototronic photodetection device based on the MoS2–water heterojunction. The combination of simple fabrication process, polarization sensitivity, and high responsivity makes the MoS2–water heterojunction an attractive candidate for dual steady-state and transient-type photodetectors.
