摘要：

A square four point probe is constructed to measure anisotropic conductivity of small samples. The method is applied to measurements of the anisotropic conductivity of a conjugated polymer. The polymer poly[3-(4-octylphenyl)-2,2'-bithiophene] is stretch oriented to various elongations and doped with I-2 vapour. The conductivity anisotropy is dependent on the degree of orientation and the absolute conductivity. Anisotropy values of 2.4 is obtained for an elongation of 4 times. For a given elongation the conductivity anisotropy decreases during the spontaneous undoping. The experimental results are discussed in terms of varying charge hopping distances.
