Question

Electrons are majority carriers and trivalent atoms are the dopants.In an n-type silicon, State true/false.

Answer 1

your question is incomplete, a complete question is -----> In an n-type silicon, which of the following statement is true:
(a) Electrons are majority carriers and trivalent atoms are the dopants. 
(b) Electrons are minority carriers and pentavalent atoms are the dopants. 
(c) Holes are minority carriers and pentavalent atoms are the dopants. 
(d) Holes are majority carriers and trivalent atoms are the dopants.

solution :- option (c) is correct choice.
n - type semiconductor can be produced by doping impurity atoms of valance 5(pentavalent atoms) for example , phosphorus.
