Carrier diffusion current arises primarily because of?

  • AA spatial carrier-concentration gradient
  • BA perfectly uniform carrier concentration
  • CZero temperature only
  • DAn ideal short circuit
Report an error
Correct Answer: A. A spatial carrier-concentration gradient
Explanation: Diffusion results from random carrier motion combined with a concentration gradient, producing net transport from higher to lower concentration.
Reference: Standard semiconductor electronics: diffusion current
