Light emitting diode

{
  "id": "MLC-T-CHM-006582",
  "term": "Light emitting diode",
  "field": "Chemistry",
  "definition": "A semiconductor device that produces light when an electric current flows through it. Electrons and holes recombine within the semiconductor material, releasing energy as photons. The specific wavelength, and thus color, of the emitted light is determined by the band gap energy of the semiconductor material.",
