What Does PEYS Stand For?

PEYS stands for Photoelectron Yield Spectroscopy

Photoelectron Yield Spectroscopy (PEYS) is an analytical technique used to measure the number of photoelectrons emitted from a material when it is illuminated by light. This method provides valuable insights into the electronic properties and surface states of materials, making it essential in fields such as materials science, nanotechnology, and surface chemistry. PEYS is particularly useful for studying the energy distribution of emitted electrons, facilitating the exploration of various phenomena, including surface reactions and electronic transitions.
