The electric conductivity and dielectric properties of Tl(GaS2)1 – x(InSe2)x solid solutions

详细

The effect of composition and temperature on the electrical conductivity and the permittivity of the Tl(GaS₂)_{1 – x}(InSe₂)_x has been studied. It is found that the permittivity and the conductivity increase with temperature and vary linearly as the InSe₂ concentration increases: in this case, the conductivity decreases and the permittivity increases. It is confirmed that the system under study contains two series of solid solutions. It is shown that the commensurate–incommensurate phase transition temperatures shift to lower values as the InSe₂ concentration increases.
