Effect of Silver Doping on the Dielectric Properties of TlInSe2 Single Crystals

详细

We have studied the effect of doping with silver on the dielectric properties and ac conductivity of TlInSe₂ (2 mol % Ag) single crystals grown by the Bridgman–Stockbarger method using a growth charge synthesized from high-purity chemical elements. Experimental data on the frequency dispersion of dielectric coefficients and electrical conductivity in (1 – x)(TlInSe₂) ⋅ xAg single crystals allowed us to identify the nature of the dielectric loss and the mechanism of hopping charge transport and evaluate parameters of localized states in the band gap.
