Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1The Fermi levels of both p-type and n-type semiconductors move upward for T > TF.
- 2The Fermi levels of both p-type and n-type semiconductors remain unaffected.
- 3The Fermi level of p-type semiconductors moves downward and the Fermi level of n-type semiconductors moves upward.✓
- 4The Fermi level of p-type semiconductors moves upward and the Fermi level of n-type semiconductors moves downward.
Correct answer
The Fermi level of p-type semiconductors moves downward and the Fermi level of n-type semiconductors moves upward.
