Luttinger liquid ARPES spectra from samples of Li$_{0.9}$Mo$_6$O$_{17}$ grown by the temperature gradient flux technique

TL;DR

This study demonstrates Luttinger liquid behavior in ARPES spectra of Li$_{0.9}$Mo$_6$O$_{17}$ samples grown by a temperature gradient flux technique, confirming the robustness of the phenomenon across different growth methods.

Contribution

It shows that the observed Luttinger liquid behavior is independent of the sample growth technique, resolving discrepancies in previous photoemission studies.

Findings

Luttinger liquid behavior observed in samples grown by the flux technique

Sample growth method does not affect the ARPES spectra significantly

Results are consistent with previous studies using different growth methods

Abstract

Angle resolved photoemission spectroscopy line shapes measured for quasi-one-dimensional Li$_{0.9}$Mo$_6$O$_{17}$ samples grown by a temperature gradient flux technique are found to show Luttinger liquid behavior, consistent with all previous data by us and other workers obtained from samples grown by the electrolyte reduction technique. This result eliminates the sample growth method as a possible origin of considerable differences in photoemission data reported in previous studies of Li$_{0.9}$Mo$_6$O$_{17}$.
