Applications of ferroelectric materials

ferroelectric materials have following applications:

(a) As Capacitors: Ferroelectric materials can be used to make capacitors.

(b) As Varactors: The value of dielectric constant for ferroelectric materials can be changed depending upon the change in the magnitude and directions of electric field. If it happens, then they can be made to behave like varactors.

(c) As Radio frequency power amplifiers: Change in electric field changes dielectric constant and this is then changes the power supply. Change in the field modulate the frequency and it means that the ferroelectric capacitors can be used as radio frequency power amplifiers.

(d) As computer memories:.Very thin ferroelectric crystals can be

used for crystal memories.
