Q. In a GaAs n-type specimen, the current generated is constant irrespective of the electric filed applied to the specimen.

  • (A) true
  • (B) false
  • (C) ---
  • (D) ---

Explanation by: Admin

in a gaas n-type specimen, when the electric field applied reaches a threshold value of eth, the current in the specimen becomes suddenly oscillatory and with respect to time and these oscillations are in the microwave frequency range. this effect is called gunn effect.
