In a semiconductor, carrier mobility is defined as the ratio of drift velocity to?

  • AApplied electric field
  • BCarrier concentration
  • CDiffusion length
  • DJunction voltage only
Report an error
Correct Answer: A. Applied electric field
Explanation: In the low-field region, drift velocity v_d = mu E, so mobility is v_d/E.
Reference: Standard semiconductor electronics: carrier mobility
