I have been recently studying the photoelectric effect and electron emission from metals. I am curious about how (if at all) this could affect the material properties of the metal, like the resistivity or stress/strain.
tarunjot said:so doesn't photoelectric effect, affect any of the material properties at all??
electron emission..such vibrations and all.. any other characeristic changes occurring??
The PhotoElectric Effect refers to the phenomenon where photons of light can transfer their energy to electrons in a metal, causing them to be emitted from the surface of the metal.
The PhotoElectric Effect can cause changes in the electrical conductivity, melting point, and surface morphology of a metal. It can also lead to the formation of a surface layer of atoms with different properties.
The intensity of light, the frequency of the light, and the properties of the metal (such as work function and electron density) are all factors that can influence the PhotoElectric Effect.
The PhotoElectric Effect is important in modern technology because it is the basis for many devices such as solar panels, photodiodes, and photocells. It also plays a crucial role in understanding the behavior of light and matter at the atomic level.
The PhotoElectric Effect was first discovered by German physicist Heinrich Hertz in 1887. However, it was not fully understood until Albert Einstein proposed his theory of photons in 1905, for which he received the Nobel Prize in Physics in 1921.
