The subject of this thesis is the growth and analysis of high temperature superconductor (HTSC) films and the study of their electronic structure and properties. In particular, the effect of epitaxial strain is investigated, predominantly by means of in-si ...
We have exploited angle-resolved photoelectron spectroscopy (ARPES) to study the electronic structure of single crystal samples of high T-c material Bi2Sr2CaCu2O8+delta and of the antiferromagnetic insulator Sr2CuO2Cl2. As one moves away from optimal dopin ...
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 ...
Photoelectron spectroscopy reveals a striking correspondence between charge-density-wave-related phase transitions and modifications of the electronic structure in 1T-TaS2. High-energy-resolution spectra indicate that the collapse of the Fermi surface is a ...
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 ...
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 ...
The ground states of the one-dimensional Falicov-Kimball model are investigated in the small-coupling limit, using nearly degenerate perturbation theory. For rational electron and ion densities, respectively, equal to p/q, pi/q, with p relatively prime to ...
We have studied by high resolution ARPES the spectroscopic properties of the prototype charge density wave system (TaSe4)(2)I and of the closely related insulating compound (NbSe4)(3)I. We observe features dispersing with the lattice periodicity, including ...
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 ...
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 ...
