Addressing the weak optical absorption of graphene

Graphene-based photodetectors have attracted strong interest because of their exceptional physical properties, which include an ultra-fast response across a broad spectrum, a strong electron–electron interaction and photocarrier ...

Biomimetic photodetector 'sees' in color

(Phys.org) —Rice University researchers have created a CMOS-compatible, biomimetic color photodetector that directly responds to red, green and blue light in much the same way the human eye does.

Self-powered wireless light detectors

Light detectors are used extensively in daily life as brightness sensors and as receivers for remote control devices in electrical gadgets, for example. However, operating these detectors requires electrical energy, which ...

World's highest quantum efficiency UV photodetectors developed

Researchers from Northwestern University's McCormick School of Engineering and Applied Science have developed the world's highest quantum efficiency ultraviolet (UV) photodetector, an advance in technology that could aid ...
