For a \(p\)-type semiconductor, which of the following statements is true?
1 Electrons are the majority carriers and trivalent atoms are the dopants.
2 Holes are the majority carriers and trivalent atoms are the dopants.
3 Holes are the majority carriers and pentavalent atoms are the dopants.
4 Electrons are the majority carriers and pentavalent atoms are the dopants.
Explanation:
In \(p\)-type semiconductor, an intrinsic semiconductor is doped with trivalent impurities, that creates deficiencies of valence electrons called holes which are majority charge carriers.

To a germanium crystal equal number of aluminium and indium atoms are added. Then
1 It remains an intrinstic semiconductor
2 It becomes a \(n\)- type semiconductor
3 It becomes a \(p\) - type semiconductor
4 It becomes an insulator
Explanation:
\(p \)- type semiconductor is formed when germanium crystal is doped with trivalent impurities i.e., having three valence electrons.

The impurity atoms with which pure silicon should be doped to make a \({p}\)-type semiconductor are
1 Phosphorus
2 Antimony
3 Boron
4 Silver
Explanation:
\({p}\)-type semiconductor is obtained when silicon is be doped with trivalent impurity like \({{Al}, {B}}\), In etc. So correct option is (3)
