The origin of the sharpness of the maximum in the phonon thermal conductivity of (Ta1−xNbxSe4)2I at low temperature [link]Website  abstract   bibtex   
Thermal conductivity (K) studies are reported on alloys of the linear-chain compound (TaSe4)2I either pure or doped with Nb, in the low-T regime. K(T) varies like T3 at very low temperatures, in agreement with the boundary scattering regime. At higher T, there is a deviation from T3 , towards Tn with n ≲ 2, for doped samples, which can be explained by a scattering process related to impurities. A sharp anomaly appears in the case of pure and doped (1 at% Nb) alloys around 1 and 1.8 K, respectively, which can be related to very unusual phonon properties of these materials and suggests a possible explanation by the Poiseuille effect.
