Poole-Frenkel effect

{
  "id": "MLC-T-CHM-009263",
  "term": "Poole-Frenkel effect",
  "field": "Chemistry",
  "definition": "The phenomenon where the electrical conductivity of an insulator or semiconductor increases significantly in the presence of a strong electric field. This effect is attributed to the field-assisted thermal emission of electrons from traps into the conduction band. It is often observed in polymeric materials used in electronic devices.",
