A new ultrathin photodetector captures light across the full spectrum in just 125 picoseconds, opening the door to faster, smarter imaging technologies.

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 ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date that works by absorbing heat generated by incoming light.

Military-grade infrared vision goggles use detectors made of mercury cadmium telluride, a semiconducting material that’s particularly sensitive to infrared radiation. Unfortunately, you need to keep ...

Electrical engineers at Duke University report they have built a record-setting pyroelectric photodetector that uses trapped light in a plasmonic nanogap to capture a signal in just 125 picoseconds ...

(Nanowerk Spotlight) For decades, researchers have sought to understand and harness the pyroelectric effect in biological materials. Pyroelectricity refers to the phenomenon where heating or cooling a ...

Pyroelectric materials are able to convert any incident radiation into a signal, allowing them to sense wavelengths from UV through to THz. DLaTGS in particular is very sensitive, meaning a higher ...

Deuterated Lanthanum α Alanine doped TriGlycine Sulphate, or DLaTGS for short is a crystalline structure that offers the strongest pyroelectric effect. Pyroelectric materials are able to convert any ...
