We briefly review some recent photoelectron spectroscopy (PES) studies of quasi one- and two-dimensional metallic systems. We discuss the spectral features of a metallic system, the expected fingerprints of the metal-insulator transition and some experimen ...
Photoelectron spectroscopy with very high energy resolution reveals both dramatic and subtle changes in the electronic density of states of the quasi-2D material 1T-TaS2, in coincidence with transitions between different charge density wave phases. Our res ...
Dispersing 1D bands have been observed for the first time in an organic conductor by high resolution photoemission experiments on TTF-TCNQ (tetrathiafulvalene-tetracyanoquinodimethane). Their properties are extremely unusual: the bandwidth is much larger t ...
Random defects destroy long-range phase coherence, and inhibit the metal-insulator transition in the charge density wave (CDW) system 1T-TaS2. Photoelectron spectroscopy with high resolution reveals corresponding changes in the electronic structure. Core l ...
Random defects destroy long-range phase coherence, and inhibit the metal-insulator transition in the charge density wave (CDW) system IT-TaS/sub 2/. Photoelectron spectroscopy with high resolution reveals corresponding changes in the electronic structure. ...
We have carried out high-resolution photoemission experiments on two quasi-one-dimensional compounds: K0.3MoO3 and (TaSe4)2I. In both systems, a metal-insulator transition associated with a lattice distortion is reported. We show that the Fermi-step charac ...
We present a photoemission study of the initial growth stages of amorphous Si on the InP(110) cleaved surface, performed at 120 K and compared with the room-temperature (RT) results. Deposition at low temperature gives a larger valence-band discontinuity w ...
