Sentences with phrase «incoming photons of light»

A gold electrode coated with nanoclusters of indium phosphide absorb incoming photons of light (that is the wavy line marked «hv» in the image).

Not exact matches

Even when you send packets as light pulses down fiber - optic cables thousands of miles long, repeaters buried every 20 miles or so on the seafloor absorb incoming photons and transmit new photons to the next repeater.

But in standard solar cell materials this requires that incoming photons have at least 5 electron volts worth of energy, which corresponds to photons of deep ultraviolet light (UV).

In the first step, incoming photons — packets of light — are converted to pairs of negatively - charged electrons and corresponding positively - charged «holes» that then separate from each other.

An incoming photon will then knock an electron from the top to bottom energy rungs, kicking out two identical photons in the process and causing amplification of light.

When both members of the pair became excited, one of them would normally fall to the lower rung before being struck by an incoming photon, producing no photon along the way and leaving too few excited electrons to make laser light.

Using a specially developed light source that generates single photons, a new A * STAR study finds that a rod cell has an almost one - in - three chance of detecting an incoming photon.

A chemistry professor at UC Santa Cruz, working with teams from California, Mexico and China, has published a paper reporting a breakthrough which may improve the conversion efficiency of incoming light photons to electrical current by as much as three times.The material developed by Jin Zhang relies on two existing technologies from the field of nanotechnology.
