Unusual spectral signatures of organic 1D metals

We have studied by high resolution angle resolved photoelectron spectroscopy the spectral properties of two metallic and one insulating Bechgaard salts, quasi-1D organic materials. The spectra of the metals show no dispersing quasiparticle peak crossing the Fermi level. Instead a deep pseudogap is observed. The spectral lineshape is incompatible with that of ''normal'' metals. The spectrum of the insulator exhibits a real energy gap.
