Vedclass · Answer

(D) $p-$type semiconductor is formed when a semiconductor is doped with an impurity that has fewer valence electrons than the host material,creating an electron deficiency or 'hole'.$Ge$ doped with $P$ ($Group$ $15$) creates an $n-$type semiconductor due to extra electrons.$Si$ doped with $S$ ($Group$ $16$) creates an $n-$type semiconductor.$NaCl$ yellow crystals are due to $F-$centers (anionic vacancies),not semiconductor behavior.$Cu_{1.98}O$ is a metal-deficient oxide. Here,some $Cu^+$ ions are replaced by $Cu^{2+}$ ions to maintain electrical neutrality,creating 'holes' in the lattice. This makes it a $p-$type semiconductor.

Which of the following can act as a $p-$type semiconductor?
