Abstract
The coercive field of KNO3 films 75 to 400nm thick is found to satisfy the empirical relation EC ∼d −1.3, where d is the thickness, in agreement with earlier work on BaTiO3 by Stadler and on TGS by Hadni et al. The switching times for large area devices (20Ox200μm) vary as E−1.5 in agreement with early work on BaTiO3 by Stadler and Zachmanidis, and indicate that the limiting parameter is the velocity of domain growth perpendicular t o the applied field.Keywords
