Question

When boron is added as an impurity to silicon, the resulting material is (A) n-type semiconductor (B) n-type conductor (C) p-type conductor (D) p-type semiconductor

Tardigrade Admin · Accepted Answer

Boron is a trivalent impurity having three valence electrons. When it is introduced to pure silicon, then such type of semiconductors are called p-type or acceptor type semiconductors.
