Photodetrapping

{
  "id": "MLC-T-CHM-008845",
  "term": "Photodetrapping",
  "field": "Chemistry",
  "definition": "The process by which charge carriers, previously immobilized in trapping sites within a material, are released into a mobile state through the absorption of photons. This optical excitation provides the energy necessary to overcome the binding energy of the trap. Photodetrapping is a key mechanism in the operation of some photoconductive devices.",
