This allows the bulk conductivity of the ferroelectric material to be increased without substantially degrading its ferroelectric domain properties.
The square-wave voltage impulse signal is biased on a ferroelectric medium film to make the polarization reversal of the ferroelectric domain.
The regions of a ferroelectric crystal with uniformly oriented polarisation are called ferroelectric domains and the plane separating two domains is called a domain wall.
A polarization reversal current is adjusted to achieve adjustments of the polarization reversal speed of the ferroelectric domain by adjusting a resistance value of the variable resistor (130).
