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

Abstract: 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, su… Show more

“…Here we reproduce the TSDC spectrum of the poled glass in temperature interval 100−400 K already described in our previous work. 24 The spectrum is presented in Figure 3a. We have included these data in the present communication because the purpose of this work is to give in the same article a complete picture of the phenomena and mechanisms under study in the full relevant temperature range, that is, in the range where these phenomena can be observed.…”

“…Relaxation test was conducted with both simulation and experiment for other glass networks. 43,44 Obata et al suggested that the mechanism of polarization and depolarization occurs when the ions propagate along the electric field and hop in the bulk. Several studies recorded the gradual damping after only few tens of hours of relaxation under different conditions of temperature and humidity.…”
