Photocarrier

{
  "id": "MLC-T-CHM-008808",
  "term": "Photocarrier",
  "field": "Chemistry",
  "definition": "A mobile charge carrier, either an electron or a hole, generated within a material upon the absorption of a photon. In semiconductors, photon absorption with energy greater than the band gap excites an electron from the valence band to the conduction band, creating a negative photocarrier (electron) and a positive photocarrier (hole). These photocarriers are responsible for photoconductivity and can drive photochemical reactions at the material's surface.",
