  "id": "MLC-T-CHM-013028",
  "term": "Depletion layer",
  "field": "Chemistry",
  "definition": "A region within a semiconductor material or at a semiconductor-electrolyte interface that is depleted of mobile charge carriers. This layer forms due to the diffusion of charge carriers across a junction, leaving behind immobile ionized dopant atoms. The width of the depletion layer is influenced by factors such as doping concentration and applied bias voltage.",
