摘要: Abstract The frequency dependent conductivity of amorphous compounds can frequently be explained by the Correlated Barrier Hopping (C.B.H.) model. This model leads to an integral which has no analytical solution and therefore is solved means approximations. We proposed a numerical calculation integral. experimental law σ' (ω) = Aωs been found. shows that this longer valid if potential energy WM lower than limitating value W1 depends on temperature static permittivity. dependence parameter s confirmed. approach proves clearly limits specifies physical signification different parameters.
