Faced with the major industrial challenges in the field of electrochemical energy storage, a fundamental research effort on the materials involved and their interfaces is nowadays essential for a gain in performance, durability and safety.In this context, it is essential to understand the interfacial processes involved that induce the degradation of the lithium metal-electrolyte interface and lead to a decrease in Coulombic efficiency and promote dendritic growth.In this thesis, we propose a study coupling electrochemical techniques such as impedance spectroscopy with surface analysis techniques such as X-ray photo-emission spectroscopy to study the chemical and electrochemical reactivity between electrolytes and a lithium metal electrode.To this end, special attention has been paid to the ionic liquids based electrolytes, which have been proposed as solvents for lithium salts, particularly for their low saturation vapor pressure, which considerably increases the safety of the batteries thus designed.Finally, this work was devoted in particular to the development of operando XPS assemblies and measurements in order to follow the chemical evolution of the interfaces inside a battery in real time

This work uses lab-scale hard X-ray photoelectron spectroscopy (HAXPES) in the perspective of inelastic background analysis (IBA) for applications in the metrology field in order to provide thickness measurements of technologically relevant materials in memory and power devices. We seek to meet the need for a method adapted for inline processes and routine analysis. The samples presented in this work were fabricated by pre-industrial processes and are representative of real device technology with concerns like complex interdiffusion properties and deeply buried active layers and interfaces. In this work, we evaluate the HAXPES-IBA technique executed with QUASES software by studying the free parameters, the operator contributions, and uncertainty in the depth distribution. We present a self-contained analysis by accessing high energy photoelectron spectra of elements from each sample layer recorded with a novel lab-scale HAXPES instrument (PHI Quantes) fitted with a Cr Kα photon source (hv = 5414.72 eV). First, highly controlled reference samples of known thicknesses (Al2O3 and HfO2 thin films) were studied to confirm the accuracy of the IBA method through validation against highly quantitative reference techniques. HAXPES-IBA thickness determinations of bilayer samples with a thick overlayer up to 25 nm and a buried layer of approximately 2.5 nm were found to be in excellent agreement with results from X-ray reflectivity (XRR) with fitting uncertainty of the IBA solution in the sub-nanometer range. The need to select the appropriate HAXPES excitation energy depending on total film thickness was demonstrated thanks to complimentary HAXPES measurements recorded with Ga Kα radiation (hv = 9251.74 eV). Finally, we apply the method to realistic technological samples. In the first study, we present thickness results from a sample class of Al2O3 films deposited over GaN by atomic layer deposition (ALD), representative of a recessed gate MOS channel High Electron Mobility Transistor (HEMT). Quantitative secondary ion mass spectrometry (SIMS) measurements compliment the IBA technique by confirming need for reference spectrum. In the second study, the HAXPES-IBA method is combined with ion sputtering to confirm the Ti/TiN overlayer thickness in a Ti/HfO2-based structure used for oxide resistive random access memory (OxRRAM) technology. We provide a critical summary of advances to reach for an accurate and reliable HAXPES-IBA method fully-integrated into inline process control

The physical properties of materials like magnetism, electric conductivity or reactivity are due to the outtermost electrons of atoms. Experimental techniques, based on the interaction between photons and matter like X-ray Photoelectrons Spectroscopy, X-ray Absorption Spectroscopy, or X-ray Magnetic Dichroism are powerful tools to study and to understand the behavior of such electrons. In the first part of this thesis, rare earths compounds have been studied. The 4f electrons of these elements, which generaly carry a strong magnetic moment, confer to these compounds original magnetic properties which are useful for various technological applications. In the rare earths series, the samarium presents atypical magnetic properties and seems to be an exception: the spin momentum makes up for the orbital momentum, which results in a weak total atomic magnetic momentum. Two studies concerning samarium compounds illustrating the capacities of the magnetic dichroism to probe magnetic properties of materials are presented in this thesis. A linear magnetic dichroism study gave the value of the magnetic moment of samarium in an antiferromagnetic thin film of metallic samarium. A magnetic circular dichroism study on the Sm1-xGdxAl2 (x=0, 1, 0. 025) system, at the samarium and gadolinium L2,3 edges, also allowed to explain the origin of the compensation point, where the magnetization cancels, observed in the temperature dependent magnetization measurements. In the second part of this thesis, we have investigated the electronic structure of oxides using resonant spectroscopies. Resonant spectroscopies consist in measuring photoemission or decay processes (fluorescence or Auger) for photons energies around an absorption threshold. Resonant Auger measurements allowed us to locate and to quantify 1s?3d quadrupolar transitions at the titanium K-edge in TiO2, thanks to the analysis of intensity of spectator lines which appear in the resonant Auger spectra and are due to the additional 3d electron. Resonant spectroscopies also allowed us to understand the titanium L2,3M2,3V Auger decays lineshape in various oxides. These decays, which involve the valence band, are very sensitive to the titanium degree of oxidation, and are very useful for the characterisation of titanium oxides surfaces, or of thin films deposited on these surfaces. The resonant study of the Auger spectra and of the valence band, completed by Auger electrons-titanium 2p photoelectrons coincidences measurements, allowed us to link the Auger lineshape and the degree of oxidation of titanium

A new family of a rare-earth ferroelectric Tetragonal Tungsten Bronze (TTB)-type compounds, with general formula Pb2(1-x)K1+xGdxNb5O15 (PKGN) was elaborated by solid state reaction. Structural and electrical properties were investigated using X-ray diffraction and dielectric measurements. Ferroelectric phases are found, and their symmetry, together with the transition temperature strongly depended of the gadolinium concentration. It was shown that at room temperature, for the low gadolinium (Gd) concentration (x < 0. 3) the ferroelectric state is described by the symmetry group Cm2m, while at intermediate Gd concentration (0. 35< x < 0. 70) the symmetry group is mainly described in Pba2 and in compounds with a higher Gd concentration, the space group P4bm is associated to ferroelectricity. The ferroelectric/paraelectric transition temperature strongly changes with the gadolinium concentration, in a non monotonic way. This behavior is due to the existence of structural changes versus composition. Two phase transitions were evidenced for compounds with higher gadolinium rate, where the intermediate phase could be related to an antiferroelectric state. The obtained results were also confirmed by Raman spectroscopy studies which provide strong evidence of the reduction of the disorder in the TTB structure when going from Pb to Gd
