A
Aluminium
B
Silicon
C
Gallium
D
Phosphorous
Correct Answer
Phosphorous
Detailed Explanation
Aluminium is not suitable for doping group 14 semiconductors.
Silicon is a group 14 element and is not suitable for doping itself for the purpose of converting it into an n-type semiconductor.
Gallium is a group 13 element and is not suitable for doping group 14 semiconductors.
Phosphorous is a group 15 element and has five valence electrons, making it suitable for doping group 14 semiconductors to create an n-type semiconductor.
Therefore, the correct answer is:
- Phosphorous.
