Abstract: After the discovery of piezo- and pyroelectricity in Polyvinylidene Fluoride (PVDF) and its copolymer with trifluoroethylene (PVDF-TrFE), numerous research initiated on their applications in ...

A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a signal in just 125 picoseconds, making it the fastest pyroelectric detector ...

Metasurfaces featuring tailored silver nanocubes could allow thermal photodetectors to approach speeds akin to traditional digital cameras. (Nanowerk News) Electrical engineers at Duke University have ...

As metasurfaces trap and localize optical energy, thermal photodetection begins operating at response times measured in picoseconds rather than conventional slow thermal scales. Maiken Mikkelsen ...
