An electron in excess of the thermal-equilibrium number and, for metals, having energy greater than the Fermi level. In semiconductors, the energy must be a definite amount above the edge of the conduction band. Hot electrons or holes can be generated by photo- excitation, tunnelling, minority-carrier injection or Schottky emission over a forward-biased p-n junction, or by abnormal electric fields in non-conductors,
