photoelectron
Light-liberated charge carrier
A photoelectron is an electron ejected from an atom or material when struck by a photon of light or other electromagnetic radiation.
The phenomenon underlies technologies from solar cells to medical imaging.
Photoelectron spectroscopy analyzes materials by measuring the energy of electrons released when surfaces are illuminated.
