Abstract
Thermally stimulated polarization and depolarization currents were measured for thin films of lithium-sodium disilicate glasses. As reported previously two thermally stimulated depolarization current peaks were found. The low-temperature peak was attributed to conduction polarization of alkali ions, while the high-temperature was attributed to localized motion of non-bridging oxygens in the alkali-depleted region near the anode rather than to space charge or interfacial polarization, as proposed earlier. Although the high-temperature peak was dominant under medium polarizing conditions, it was swept away irreversibly by biasing at extremely high electric field.
