Abstract

The electronic properties of the quasi-one-dimensional (1D) oxide conductor Li0.9Mo6O17have been investigated using high-momentum and energy resolution photoelectron spectroscopy at temperatures above and below the metal-semiconductor transition temperature. Considerable spectral intensity at the Fermi energy (EF) is observed at room temperature, and a sharp feature corresponding to a band crossing EF is clearly resolved for states along the quasi-1D axis. Below the metal-semiconductor transition at 24 K, a gap is clearly observed to open at EF. Our data do not support the assertion that the low energy excitations of electrons in Li0.9Mo6O17should be described in a Luttinger liquid model.
