The mechanism of electrical conductivity and thermal conductivity of AgSbSe₂

It was investigated the electrical conductivity and thermal conductivity of AgSbSe₂ in the 80-330K temperature range. It was shown, that charge transfer in AgSbSe₂ is carried out by means of hopping conductance of carriers over localized states. The radius of the localized state and the density of localized states at the Fermi level are calculated. It was shown that a high defectiveness of AgSbSe₂ leads to a low value of the lattice thermal conductivity.
