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 exploited resonant photoemission at the Ce 4d --> 4f absorption edge to investigate the Ce 4f states in CePd3. High resolution spectra reveal, near the Fermi level, the characteristic fine structure of intermediate valence Ce compounds. The spectral lin ...
A new type of material consisting of an amorphous silicon matrix, in which silicon nanoparticules are embedded, has recently been obtained. This material, named polymorphous silicon (pm-Si), exhibits enhanced transport and stability properties with respect ...
The reflectivity of TmS single crystals has been measured between 3 meV and 12 eV at room temperature and at 6 K, Besides 3p(6)-5d interband transitions a plasma edge due to free carriers is observed. In the middle infrared (near 50 meV) two sharp lines ar ...
We report high resolution angle-scanned photoemission and Fermi surface (FS) mapping experiments on the layered transition-metal dichalcogenide 1T-TaS2 in the quasicommensurate (metallic) and the commensurate (insulating) charge-density-wave (CDW) phase. I ...
The density of states at the Fermi level N(E-F) has been measured on hydrogenated polymorphous (pm-Si:H) silicon samples using both capacitance measurements on Schottky barriers and space-charge-limited current measurements on n(+)/i/n(+) structures. From ...
We performed optical and photoemission experiments on the Bechgaard salt (TMTSF)(2)ReO4, a quasi-one-dimensional (1D) organic conductor that undergoes a metal-insulator (Peierls) transition at T-c similar to 180 K. As in other compounds of the same family, ...
We have exploited the resonant enhancement of the Ce 4f cross section around 120 eV to investigate the nature of the 4f states in CePd3 and CeSb. Our results are qualitatively consistent with the predictions of the Anderson Impurity Model. In CePd3 our hig ...
Differently prepared surfaces of quasicrystalline i-Al-Pd-Mn are analyzed using angle-resolved photoemission in the X-ray and ultraviolet range of photon energies. Depending on the preparation, we find both surfaces with crystalline structure and metallic ...
We have exploited angle-resolved photoelectron spectroscopy to study changes in the quasiparticle excitations of CuO2 planes as a function of the carrier density, in optimally doped and underdoped Bi2Sr2CaCuO8+x and in Sr2CuO2Cl2. We have observed large ch ...
