Differences in the Kinetic Characteristics of Charging Ferroelectrics and Dielectrics upon Ion Irradiation

Comparative studies are performed on the fundamental characteristics of charging classical dielectrics (PMMA) and ferroelectrics (LiNbO 3 ) upon ion irradiation. Samples in experiments are irradiated with Ar + ions having energies of 5–10 keV. General patterns are revealed in the kinetics of chargin...

Description
Summary:Comparative studies are performed on the fundamental characteristics of charging classical dielectrics (PMMA) and ferroelectrics (LiNbO 3 ) upon ion irradiation. Samples in experiments are irradiated with Ar + ions having energies of 5–10 keV. General patterns are revealed in the kinetics of charging and typical differences in the characteristics of the current of the emitted ions, the displacement current (charge accumulation), and the surface potential. The first characteristic feature of charging ferroelectrics is the emergence of additional current in the detecting devices (the current of repolarization). The second feature is the presence of a double layer of charges on the surfaces of ferroelectrics. This double layer affects all kinetic characteristics of charging.
