When a dielectric is irradiated by electrons with energy E of several kiloelectron volts, a large number of processes take place: backscattering of incident electrons, excitation and ionization of the electrons in the dielectric with binding energies

Electron-induced X-ray emission spectroscopy (EXES) combined with a semi-empirical electron scattering model, which describes the ionizations inside a material under electron irradiation, is used to determine the depth profile of shallow and ultra-sh

Nous presentons les modulations d'intensite de la raie Si Kα emise par une structure multicouche en fonction de l'angle de sortie des photons. L'observation est realisee autour de la direction correspondant a la direction de Bragg de la raie Si Ka p

We give the design of tunable and bright EUV sources based on the interaction of medium-energy electrons with periodic multilayer targets. The basic phenomon is the Bragg resonant transition radiation occurring when transition radiation is diffracted

An novel interpretation of Ba 4d spectrum observed in BaF2 excited by a discrete photon radiation is proposed, based on a model of collisional redistribution following a first order excitation process. In the case of Ba2+ and neutral barium, we perfo

Study of an α-Al2O3 single crystal by electron-induced x-ray emission spectroscopy and cathodoluminescence is reported. The relative intensities of optical emissions due to F+ and F centers have been determined as a function of the parameters of the

The energy distribution of oxygen 2p states is studied at the Cu/MgO(100) interface in a zone of 1.5 nm buried under a 10 nm thick copper film. Occupied oxygen states are evidenced in the MgO band gap. The results are deduced from an analysis of the

The relative intensity of the Mg $K\ensuremath{\beta}$ emission band with respect to the $K\ensuremath{\alpha}$ atomic line, obtained by electron-induced x-ray emission spectroscopy, is used to investigate the variation of $p$-like valence electron n

With the aim of studying the physicochemical interactions in metal-ceramic interfaces, we have investigated the Cu-MgO system. Two kinds of interfaces prepared at room temperature have been studied: interfaces during their formation (studied by X-ray

The model called IntriX, designed to interpret quantitatively electron probe analysis data, was tested via confrontations between its results and experimental or Monte Carlo data. These confrontations were established for in-depth ionization distribu
