Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, ...

We report a monolithically integrated ultraviolet (UV) photoelectric switch based on a GaN-on-silicon platform for the first time. The novel integrated switch consists of a U-shaped trench metal-oxide ...

Einstein’s heuristic argument that light consists of packets of energy or light quanta could explain the energy dependence of electrons on the frequency of light in the photoelectric effect.

In 1921, Albert Einstein was awarded Nobel Prize in Physics for his exceptional work on the photoelectric effect and the quantum theory of light.

This outrageous idea, which earned him a Nobel Prize in Physics, explained some up-until-then unexpicable phenomena like the photoelectric effect, where an electron’s energy depended on the light’s ...

Millikan's experiments did not bring about the acceptance of light quanta. In this period (1913–1923), there was simply no convincing explanation of the photoelectric effect.

Sick of the Soap Opera Effect ruining your favorite movies and shows? Here’s how to turn this feature off on most major TVs.

The optical tuning was achieved through the photoelectric effect of the germanium absorption region on a silicon photonic platform. When light is incident on the Ge absorption region, it generates ...

1905 Quantized Light Inspired by the photoelectric effect and Planck’s theory, Albert Einstein argues that light itself travels in countable bundles of energy he calls “light quanta.” He suggests that ...

But while there is still no quantum theory of gravity, the challenge of detecting its signatures now looks a little more manageable thanks to a proposed experiment that takes inspiration from the ...

The principle behind their experiment parallels that of the photoelectric effect, in which light shining on a material causes it to emit discrete packets of energy, one particle at a time, rather than ...
