Question

Semiconductors of both p-type and n-type are produced by:
a) Ionic solids
b) Covalent solids
c) Metallic solids
d) Molecular solids​

Answer 1

Answer:

The Doping of Semiconductors

The Doping of SemiconductorsPentavalent impurities Impurity atoms with 5 valence electrons produce n-type semiconductors by contributing extra electrons. Trivalent impurities Impurity atoms with 3 valence electrons produce p-type semiconductors by producing a "hole" or electron deficiency.
