Abstract:
The temperature dependences of electrical conductivity over localized states in the solubility region of mixed crystals of compositions (TlInSe$_2$)$_{1-x}$(TlGaTe$_2$)$_x$ at $x$ = 0, 0.1 0.2, 0.8, 0.9, and 1 are studied. It is established that hopping conductivity with a variable hop length over localized states near the Fermi level occurs in this system. The conductivity activation energy is determined; and the density of states in the vicinity of the Fermi level, their dispersion, localization radius, and average carrier hop distance for all compositions are estimated; and the concentration dependences of the calculated parameters are plotted.
