Abstract

We report angle-resolved photoemission spectra (ARPES) of \ensuremathη\penalty1000-\hskip0ptMo₄O₁₁, a layered metal that undergoes two-charge density wave (CDW) transitions at 109\phantom\rule0.3em0exK and 30\phantom\rule0.3em0exK. We have directly observed the ``hidden one-dimensional (hidden 1D)'' Fermi surface and an anisotropic gap opening associated with the 109\phantom\rule0.3em0exK transition, in agreement with the band theoretical description of the CDW transition. In addition, as in other hidden 1D materials such as NaMo₆O₁₇, the ARPES line shapes show certain anomalies, which we discuss in terms of non-Fermi-liquid physics and possible roles of disorder.
