Question

What are intrinsic semiconductors ? Give an example.

Answer 1

Examples include silicon and germanium. A direct band gap intrinsic semiconductor is one where the maximum energy of the valence band occurs at the same k as the minimum energy of the conduction band. Examples include gallium arsenide.

Answer 2

⭐ $\rm\underline\red{ Intrinsic \: \: Semiconductor }$ :- Pure semiconductor like silicon is called intrinsic semiconductor.

• In an intrinsic semiconductor, number of electrons = number of holes

☄️ $\sf\underline\green{ Example \: \: :- }$

1. Silicon
2. Germanium
