Giant dielectric relaxation in TlGaTe2 crystals

The conductivity and temperature-frequency dependences of the permittivity of TlGaTe 2 crystals have been studied. Strong dielectric relaxation has been revealed. It has been shown that the mechanism of dielectric relaxation is associated with hopping of Tl ions over vacancies in the thallium sublat...

Beschreibung
Zusammenfassung:	The conductivity and temperature-frequency dependences of the permittivity of TlGaTe 2 crystals have been studied. Strong dielectric relaxation has been revealed. It has been shown that the mechanism of dielectric relaxation is associated with hopping of Tl ions over vacancies in the thallium sublattice due to the transition of the system to the superionic state.
