Physical model of retention and temperature-dependent polarization reversal in ferroelectric films

Nava Setter, Alexander Tagantsev, Enrico Colla, Igor Stolichnov

The phenomenon of time-dependent polarization loss in poled ferroelectric capacitors, also known as retention, represents one of the most important reliability issues for ferroelectric nonvolatile memories. In a number of publications different ways to con ...
