THE extensive work of Gudden, Pohl and A others has to a certain extent clarified the behaviour of insulating crystals which become electrical conductors under the influence of light. In these ...

Here’s a fun video by [Ashish Derhgawen], discussing the photoelectric effect of neon lamps with some simple demonstrations. Orange light makes it light! [Ashish] demonstrates the well-known ...

(Courtesy: TU Wien) The effect of quantum entanglement on the emission time of photoelectrons has been calculated by physicists in China and Austria. Their result includes several counter-intuitive ...

PES is based on the photoelectric effect, where a material absorbs photons and emits electrons (called photoelectrons) with specific kinetic energies. By analyzing the energy distribution of these ...
