WebFeb 8, 2024 · 5. I would say that photoemission is not a surface effect, not normally. Your understanding is correct. That said, there is also "surface photoemission" due to the p → ⋅ A → term in the Hamiltonian and symmetry breaking at the surface. As an example, see this paper about silver. Webphotoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined …
WebThis phenomenon is called the photoelectric effect. Heinrich Hertz, a German physicist, discovered the photoelectric effect in 1887. He observed that shining an ultraviolet light on electrodes caused a change in the voltage between them. Other work during the 19th century built on Hertz’s observations.
