Ferroelectric materials are characterised by
(A) Very high degree of polarisation.
(B) A sharp dependence of polarisation on temperature.
(C) Non-linear dependence of the charge Q on the applied voltage.
(D) All the above.
Ans:
Ferroelectric materials are characterised through very high degree of polarisation, a sharp dependence of polarisation upon temperature and a sharp dependence of polarisation upon temperature.
