Abstract

We report electrical resistivity measurements on the quasi-one-dimensional conductors TaSe3, Nb2Se3, and Nb3S4 in the temperature range 4.2-300 K. We find that resistivities of all three materials vary as 0+CTn in the low-temperature region, where 2<~n<~3. This behavior is discussed in light of the theory of Oshiyama et al., which shows that electron-electron umklapp scattering is dominant in quasi-one-dimensional metals with nearly planar Fermi surfaces and predicts a Tn(2<~n<~3) dependence of the intrinsic resistivity. A weaker T1 dependence is observed near room temperature, as predicted by the theory.
