उत्तर
p-type semiconductors are formed when Si or Ge are doped with group 13 elements.
Explanation:
Three valence electrons are present in group 13 elements. The fourth valence electron is absent when group 13 elements are added to Si or Ge; this hole is known as an electron hole. Through this hole, electricity is transmitted. P-type semiconductors are this kind of semiconductor.
