Photoelectron (Noun)
Meaning
An electron that is emitted from an atom or molecule by an incident photon.
Classification
Nouns denoting natural objects (not man-made).
Examples
- The energy of the photoelectron is directly related to the energy of the incident photon.
- In the photoelectric effect, the emission of a photoelectron occurs when the energy of the incident photon exceeds the binding energy of the electron.
- The kinetic energy of the photoelectron is determined by the difference between the energy of the incident photon and the work function of the material.
- Scientists use photoelectron spectroscopy to study the energy levels of atoms and molecules by analyzing the energy of emitted photoelectrons.
- The photoelectron is emitted from the atom or molecule in a specific direction, which is influenced by the polarization of the incident photon.
