To convert the Si crystal into a P. type semi-conductor, which group element be doped?
Correct answer: A. Trivalent element
- A. Trivalent element
- B. Four group element
- C. Second group element
- D. Pentavalent element
Explanation
When a few atoms of trivalent dopant replace silicon atoms in the lattice, a vacant state (or electron "hole") is created and can act as an electron carrier through the structure, which creates a p-type semiconductor.
