Ptype Silicon Is Formed By Adding A Minute Amount Of Chemistry Question

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.
