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 ...

Zinc oxide is potentially a useful material for ultraviolet detectors; however, a relatively long response time hinders practical implementation. Here by designing and fabricating a self-powered ...

Many peptides and proteins have an innate ability to assemble into long, slender fibers called fibrils and other shapes. Now, researchers have found a way to harness this property to create tubular ...

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

Practical demonstration on setup and configuration of infrared detectors. In theory, the functioning of a pyroelectric detector is absolutely comprehensible. As the centrepiece in gas analysers, flame ...

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 ...
