High‐Performing Self‐Powered Photosensing and Reconfigurable Pyro‐photoelectric Memory with Ferroelectric Hafnium Oxide (Adv. Mater. 5/2022)

Pyroelectric Sensors Hafnium oxide has gained great attention for its numerous multifunctional features. In article number 2106881, Mohit Kumar and Hyungtak Seo report a proof-of-concept HfO2-based self-powered, ultrafast (≈60 μs) infrared pyroelectric sensor with a responsivity of up to 68 μA W−1. The regulated suspension and reestablishment of the self-biased pyro-photocurrent response with a short electric pulse is demonstrated.
