noun

an electron ejected from a system by a photon striking it, or emitted as a result of radiation

photoelectron Usage Examples

Converse of object

  • eject: The pictures below show the cosine squared distribution of the ejected photoelectron in the presence of multiple scattering.
  • emit: The chemical state of a surface can also be monitored by analyzing the photoelectrons emitted from a surface on bombardment with x-rays.
  • measure: Measuring the photoelectron current at 0º and 90º to the polarization vector of the synchrotron radiation yields the polarisations, given below.
  • call: Bombardment with x-ray photons leads to the emission of electrons, these are called photoelectrons.

Modifies a noun

  • spectroscopy: X-ray photoelectron spectroscopy provides stronger evidence that the surface of these granules is modified by oxidation.
  • diffraction: Photoelectron diffraction is a method used to determine the geometry of molecules or atoms on single crystal surfaces.
  • spectra: Recent experimental studies of photoelectron spectra provide support for theories.
  • spectrum: Figure 2. ( a ) Threshold photoelectron spectrum of SF 5 CF 3 at a resolution of 0.3 nm.
  • emission: He was studying the photoelectron emission properties of diamond films.

Noun used with modifier

  • X-ray: X-ray photoelectron spectroscopy provides stronger evidence that the surface of these granules is modified by oxidation.
