A New Perspective of Negative Capacitance in Ferroelectrics

The fundamental understanding of negative capacitance is not fully complete.Ferroelectrics are like ferromagnetics in that the different areas of ferroelectrics get polarized in different directions based on the charge density and finally the net charge of the material, as a whole gives the resultant polarization in a particular direction.The negative permitivity results in opposite polarization and it can be further explained in multidomain ferroelectrics.
