The quest to understanding the properties of the one-dimensional metallic state with its various manifestations of charge density modulations, suppressed ordering and instability of the Fermi liquid state is best studied in compounds with parallel, but ideally non-interacting molecular or atomic chains. The family of M2Mo6Se6, where M represents Tl, In, Cs, Rb, or lighter alkali metals forms such a quasi one-dimensional crystal structure with a host lattice of (M36Se3) molecular chains that are weakly coupled by the M guest ions. In this seminar a thorough study of the lattice, phonon dispersions and electronic structure by x-ray diffraction, inelastic x-ray scattering (IXS) and angle-resolved photoemission spectroscopy (ARPES) will be presented.
