Photoemission Studies of Amorphous Silicon/Germanium Heterojunctions
The heterostructures obtained by growing a-Ge on a-Si:H and a-Si have been investigated by synchrotron radiation photoemission. We measured valence band and core level spectra on the heterostructures grown in ...

Study of the valence bands of FePS3 and NiPS3 by resonant-photoemission spectroscopy
We have investigated the valence bands of the tiophosphates FEPS3 and NiPS3 with the resonant-photoemission technique. Some structures of the energy distribution curves show rapid intensity changes when the photo...

Geometrical Structure of Graphitic Carbon on Ni(111) Studied by Extended Energy Loss Fine Structure Spectroscopy (EELFS)
The geometry of adsorbed atoms on ordered surfaces may be determined by different experimental techniques. Among them the most used are ion scattering spectroscopy-(ISS) [1,2], surface extended X-ray absorptio...

Valence Relaxation in the 2p Core Photoionization of Mixed Valence TmSe Crystal
The L3 X-ray absorption spectrum of TmSe has been measured using synchrotron radiation emitted by the storage ring Adone. Evidence of homogeneous mixed-valence of TmSe and of the core hole induced relaxation has ...

Optical gaps of dilute α-phase Ag-Cd alloys from thermoreflectance measurements
The fractional change in reflectivity due to temperature ΔR/R of bulk samples of four silver-cadmium alloys was measured in the energy range (2.2÷4.8) eV. The samples had cadmium concentrations of 1.5, 3.0, 6.5 a...
