  "id": "MLC-T-CHM-008852",
  "term": "Photoelectric work function",
  "field": "Chemistry",
  "definition": "The minimum energy required to remove an electron from a solid surface into a vacuum, overcoming the attractive forces holding it within the material. This energy is typically expressed in electronvolts (eV). It is a characteristic property of a material and depends on its surface condition and crystallographic orientation.",
