p-type silicon is formed by adding a minute amount of an element with
Options
(a) five valence electrons
(b) three valence electrons
(c) six valence electrons
(d) four valence electrons
Correct Answer:
three valence electrons
Explanation:
p-type silicon is formed by adding a minute amount of a trivalent elements like boron or aluminium. The three electrons of these elements form covalent bonds with the neighbouring silicon atoms. This causes an electron vacancy in the crystal. Therefore p-type silicon is formed with an element of three valence electrons.
