Diffused junction semiconductor detector

  "id": "MLC-T-CHM-003190",
  "term": "Diffused junction semiconductor detector",
  "field": "Chemistry",
  "definition": "A type of semiconductor radiation detector created by diffusing dopant impurities into a semiconductor material to form a p-n junction. When radiation interacts with the detector, it creates electron-hole pairs, which are then swept apart by an electric field across the depletion region, generating a measurable current pulse. These detectors are commonly used for detecting charged particles and gamma rays.",
