A photodiode (PD) is a semiconductor device that converts light into current. When the PD is reverse-biased, a current is generated as the PD absorbs photons. The PD also produces a small amount of ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.

CMOS image sensors have become a cornerstone of modern imaging technology, integrating photodiodes with on-chip signal processing to convert light into precise electronic data. Central to their ...

Researchers developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, and machine learning algorithms. (Nanowerk Spotlight) Conventional ...

Researchers at the University of Turku, Finland, have developed an organic infrared photodiode that achieves record-level ...
