Q. If the length of the intrinsic region in IMPATT diode is 2 µm and the carrier drift velocity are 107 cm/s, then the drift time of the carrier is:
  • (A) 10-11 seconds
  • (B) 2×10-11 seconds
  • (C) 2.5×10-11 seconds
  • (D) none of the mentioned

✅ Correct Answer: (B) 2×10-11 seconds

Explanation: the drift time of the carrier is defined as the ratio of length of the intrinsic region to the carrier drift velocity.
