Abstract

We have performed angle-resolved photoemission spectroscopy on Nb₃Te₄, which has zigzag Nb-Nb chains along the c-axis in the crystal. We found a dispersive Nb 4d band near the Fermi level (E_F) which crosses E_F midway between the center and the boundary of the Brillouin zone in the chain direction. The intensity of the Nb 4d band was found to be substantially suppressed near/at E_F, showing a typical Tomonaga-Luttinger liquid behavior of 1D metals. On the other hand, a clear Fermi-edge cutoff, characteristic of 2D or 3D metals, is seen for this Nb 4d band. All these results suggest that Nb₃Te₄ is a quasi 1D metal with admixture of 2D or 3D character due to the finite inter-chain interaction.
