Photoemission theory

Photoemission theory explains how materials emit electrons when exposed to light, particularly ultraviolet or X-ray radiation. When photons from the light hit the surface of a material, they can transfer energy to the electrons within that material. If the energy is sufficient, it can free these electrons from their atomic bonds, allowing them to escape. This process is fundamental in various technologies, such as photoelectric sensors and energy conversion. Understanding photoemission helps scientists explore material properties, electronic structures, and develop new devices in electronics and photovoltaics.
