Transport and thermal properties of single crystal TaNiTe5

Here, we study the thermal and transport properties of topological single crystal TaNiTe5 down to near 0 K and magnetic fields up to 14 T. By analyzing the variation of resistivity rho and Seebeck coefficients S with temperature T, we provide the evidence of electron-electron scattering and electron-phonon scattering in the lower and higher temperature region, respectively. The dependence of S and kappa on magnetic field H is well described by two-band model of conduction vertical bar Delta S/S vertical bar alpha H-n for various temperatures, which also suggests electron and phonon are two kinds of carriers and benefit to the thermal conduction.

Automated summary

The study investigates the thermal and transport properties of topological single crystal TaNiTe5 at temperatures near 0 K and magnetic fields up to 14 T. By analyzing the variation of resistivity and Seebeck coefficients with temperature, electron-electron scattering and electron-phonon scattering effects are observed in different temperature regions. The findings suggest that electrons and phonons act as two effective charge carriers, contributing significantly to thermal conduction.
