Solids do not have which type of polarisation?

Ionic

Interfacial

Electronic

Orientational

Correct Answer : Option (B) : Interfacial

Explanation : Solids possess permanent dipole moments. Moreover they do not have junction like semiconductors. Thus, solids neglect the interfacial and space charge polarisation. They possess only electronic, ionic and orientational polarisations.
