Semiconductor-metal transition

{
  "id": "MLC-T-CHM-010725",
  "term": "Semiconductor-metal transition",
  "field": "Chemistry",
  "definition": "A phase transition in which a material changes from a semiconducting state, characterized by a finite band gap, to a metallic state, where the band gap closes or overlaps. This transition can be induced by changes in temperature, pressure, or doping. Vanadium dioxide (VO2) is a well-known example that undergoes such a transition near room temperature.",
