Peculiarity of Low Density Plasma-Assisted Charge Emission Produced at LATGS Crystal Surface

2011

Time and energy distribution measurements for a weak plasma-assisted electron and ion emission, initiated at the surface of L-α alanine doped TGS (LATGS) single crystals by a drive ac (500 Hz) electric field exceeding 5 × 103 V/cm, have been performed especially at temperatures below as well as above phase transition. Time spectra of charges obtained at temperatures below phase transition are considerably different than that detected above phase transition; total number of charges registered under switching conditions is about an order higher than that produced during mere charging of the sample; time dependent energy spectra involve charges (electrons and ions) with energies up to a few hu…

Parameters of microdischarges occuring at surfaces of repolarized ferroelectrical materials

1993

Parameters of the microdischarges occuring at the surfaces of the repolarized ferroelectric materials have been investigated. It has been found that in the case of BaTiO3ceramic the number of microdischarges increases linearly with increasing repolarizing voltage Upp, the photoelectric parameters of individual discharges being unchanged. The photoelectric and current parameters for system with TGS are very similar but the dependence of the amplitude of the current pulses on the repolarizing voltage differs distinctly from that for BaTiO3.
