Which one of the following is NOT a correct statement about semi-conductors?
  • a)
    The electrons and holes have different mobilities in a semi-conductor
  • b)
    In an n-type semi-conductor, the Fermi level lies closer to the conduction band edge
  • c)
    Silicon is a direct band gap semi-conductor
  • d)
    Silicon has diamond structure
Correct answer is option 'C'. Can you explain this answer?

Which one of the following is NOT a correct statement about semi-cond...
Explanation:
Direct Band Gap vs. Indirect Band Gap:
Direct band gap materials have their maximum of the valence band and minimum of the conduction band at the same momentum. In contrast, indirect band gap materials have their maximum of the valence band and minimum of the conduction band at different momentum points. Silicon is an indirect band gap semiconductor, not a direct band gap semiconductor.
Therefore, the statement "Silicon is a direct band gap semiconductor" is incorrect.
