In 1905, Albert Einstein showed that the photoelectric effect—the ability of metals to produce an electric current when exposed to light—could be explained if light is quantum, traveling in discrete ...

June 9, 2022, marks 117 years since Einstein published his groundbreaking paper on the photoelectric principle. The analysis was published on June 9, 1905, also known as Einstein’s “miracle year” ...

(Nanowerk News) It is now exactly one hundred years ago that Albert Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect. The jury had not yet really understood his ...

The photoelectric effect is a phenomenon where light knocks electrons out of a material, resulting in the emission of these electrons, called photoelectrons. Albert Einstein explained the ...

In a flash: artist's impression of the photoelectric effect. (Courtesy: Technical University of Vienna) Just 45 quintillionth of a second (45 attoseconds) is all it takes for a photon to liberate an ...

According to quantum mechanics, our universe is like a Lego set. All matter particles, as well as particles such as light that act as messengers between them, come in discrete blocks of energy. By ...

However, with wavelengths of only 13 nanometers and high radiation intensities of several petawatt per square centimeter something else – at least with some atoms – happens: With xenon, a whole ...

When a photon hits a material, it can eject an electron from it provided it has enough energy. Albert Einstein found the theoretical explanation of this phenomenon, which is known as the photoelectric ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...
