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,
