  • photocathodes Photocathodes are specialized materials or surfaces that exhibit the photoelectric effect, wherein the absorption of photons leads to the emission of electrons. When photons with sufficient energy strike a photocathode, they transfer energy to the...
  • phototube An electron tube having a photocathode for the emission of a photoelectric current.
  • photoelectric effect The emission of an electron from a surface that occurs when a photon impinges upon the surface and is absorbed. This effect is the means by which photons may be detected.
  • cathode A cathode is an electrode through which electric current flows out of a polarized electrical device. In different contexts, the specific role and behavior of the cathode can vary, but it generally serves as the site for reduction reactions (gain of...
