Extrinsic semiconductor

  "id": "MLC-T-CHM-004314",
  "term": "Extrinsic semiconductor",
  "field": "Chemistry",
  "definition": "A semiconductor material whose electrical conductivity is significantly enhanced by the controlled addition of impurities, known as dopants. These dopants create either an excess of free electrons (n-type) or holes (p-type), increasing the number of charge carriers. Silicon doped with boron or phosphorus is a common example.",
  "subject": "Polymer",
