Charge carrier diffusion

{
  "id": "MLC-T-CHM-001892",
  "term": "Charge carrier diffusion",
  "field": "Chemistry",
  "definition": "The movement of charge carriers, such as electrons or holes, through a polymer due to random thermal motion, driven by a concentration gradient. This process contributes to the overall charge transport in the absence of an external electric field. The diffusion coefficient is measured in cm²/s.",
