Addressing the plasma formation on the surface of a ferroelectric sample

Abstract

A description of plasma formation on the surface of a ferroelectric sample is presented, based on simple assumptions about the electrodynamic evolution of the system along with the continuity equation for the current and the conservation of the ion flow impulse. Two models starting with these assumptions are shown capable of predicting, with satisfactory agreement to experimental data, the plasma density and temperature, and plasma propagation velocity. Also, one of the models allows one to obtain the distributions of the potential, surface charge density, and current density along the ferroelectric surface during plasma propagation.
