Ionic direct current and thermally stimulated depolarization currents in connection with the structure of alkali borate glasses

TSDC spectroscopy of relaxational and interfacial phenomena

“…Glass materials are popular objects for TSDC investigations [165][166][167][168][169][170][171][172][173][174][175][176][177][178][179][180][181][182][183] of the mechanisms of dipolar polarisation and relaxation, dc electronic and ionic conductivity. Dutt and Day [165] and Dutta and Day [166] analysed the origin of TSDC in oxide glasses.…”

“…peak had an activation energy less than that for dc conduction, and its behaviour was consistent with dipole polarisation. A series of works was devoted to glasses with Cs, Fe, Na, and Cu phosphates [167][168][169][170][171][172], alkali borate glasses [173][174][175] and multi-component glasses [176][177][178], especially their dc conductivity and the effects of composition and structure on the relaxation mechanism. The effects of irradiation of glasses [179] and defects [180] were also studied by the TSDC technique.…”

Mechanism of Thermal Charge Relaxation in Poled Silicate Glasses in a Wide Temperature Range (From Liquid Nitrogen to Glass Melting Temperature)

“…Commonly, measurements of the TSDC spectra of poled glasses are performed in narrow (restricted) temperature intervals. Most studies are performed either below the ambient temperature − or much less in the interval 300–700 K, and there are only rare works where TSDC spectra were measured above glass transition temperatures (700–1100 K). , Note that in all these studies the researchers used different glasses, so that comparison of these data does not provide a complete picture about the phenomenon in the full temperature interval in the same material. In the presented research, we have generalized our studies of TSDC spectra measured in the same poled multicomponent silicate glass in the full temperature range, starting from 100 K up to 1000 K, where all possible TSDC bands of different natures are observed.…”
