Ferroelectric materials and piezoelectric materials can be compared with the help of following points : a) In piezoelectricity, the crystal is polarized by the application
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 classified on the basis of their chemical composition and structure as : (a) Rochelle salt: The first solid to show ferroelectric
In the last article, I have discussed about ferroelectricity and hysteriesis loop. Today we will discuss about the reason of hysteresis loop. Ferroelectric crystals have
In ferroelectric materials, the polarization P does not vary linearly with electric field E. Hysteresis curve: The plot of P versus E in which the
Last time I have discussed about the piezoelectricity. Let us discuss about the applications of piezoelectric effect. (a) Electro-mechanical transducers. Piezoelectric effect is used to
Definition: When certain crystals become electrically polarized that is electric charges appear on their surface when stressed then this phenomenon is called the piezoelectric effect,
In the earlier article, I have explained the electronic polarization. Today we will discuss the ionic polarization. Ionic polarization. As the name suggests, ionic polarization
The four types of polarization which occur in dielectrics are: (I) Electronic polarization, (II) Ionic polarization, (III) Orientation or dipole polarization, (IV) Space charge or
