On the origin of the low-temperature band in depolarization current spectra of poled multicomponent silicate glasses

Thermally stimulated depolarization current spectra of poled silicate multicomponent glasses in the vicinity of room temperature (220–320 K) have been recorded and two bands, typical for such glasses, have been observed. It was shown that the high-temperature band (at about 290 K) is related to the...

Description
Summary:Thermally stimulated depolarization current spectra of poled silicate multicomponent glasses in the vicinity of room temperature (220–320 K) have been recorded and two bands, typical for such glasses, have been observed. It was shown that the high-temperature band (at about 290 K) is related to the relaxation of poled glass structure in the bulk, while the low-temperature band (at about 230–270 K) should be attributed to the surface phenomenon—absorption/desorption of positive species of ambient atmosphere, supposedly, water cluster ions H+(H2O)n.
