Gunn effect

  "id": "MLC-T-IND-002688",
  "term": "Gunn effect",
  "field": "Industrial and trades",
  "definition": "A phenomenon in certain semiconductor materials, such as gallium arsenide, where a strong electric field causes the electron velocity to decrease as the field strength increases beyond a threshold. This negative differential resistance leads to the formation of high-field domains that propagate through the material. The Gunn effect is the operating principle behind Gunn diodes, which generate microwave frequencies.",
