Answer to Question #69486 in Electric Circuits for TIGER

Question

b) Which processes are responsible for the charge carrier transport in a semiconductor?
Which of these govern in the case of a bulk semiconductor when no potential is
applied?

Answer 1

Solution:
Two processes are governing the charge transport in semiconductors
1. Drift
2. Diffusion
When no potential is applied the charge carriers in the bulk semiconductor move due to diffusion to equalize their concentration inside a material.
