Full textOver the past years, the organic optoelectronic component market has developed significantly. A particular effort is made on increasing the lifetime which is a limiting factor for these components. This limitation is mainly due to the intrusion of impurities in the electroluminescent material from electrodes. To limit the arrival of these impurities, we have made studies on the design of organic devices using a cathode obtained by ion beam assisted deposition. These studies (AFM spectroscopy, X-rays, simulation) have shown that ion assistance led to topography of the cathode surface much softer with a denser microstructure. Comparative studies of device aging (I(V), L(V), L(t)…) have also shown that ion assistance improves significantly the performance and the lifetime of the device in relation to the unassisted device. Preceding this work, we achieved an optimization of the used multilayer structure to improve the stability of OLEDs

Full textThe investigation of hydrogen in atom probe tomography (APT) presents a challenge due to its low mass, high diffusion coefficient, and presence as a residual gas in ultra-high vacuum chambers, leading to multiple complications. Various solutions have been proposed in the literature, such as ex-situ loading coupled with cryotransfer or high-temperature hydrogen loading in an adjacent chamber. However, these solutions often face difficulties due to the complex control of the specimen temperature during hydrogen loading and the transfer of the specimen for analysis. This manuscript proposes an alternative approach for in-situ hydrogen loading in an APT chamber, derived from a method developed in field ion microscopy. By applying negative nanosecond pulses to the specimen in an APT chamber under low H₂ pressure, we demonstrate that a high dose of hydrogen can be implanted at depths ranging from 2 to 20 nm beneath the specimen surface. An APT chamber was modified to enable the direct application of negative pulses with controlled gas pressure, pulse repetition rate, and pulse amplitude. Through electrodynamic simulations, we show that the implantation energy falls within the range of 100 to 1,000 eV, and a theoretical implantation depth and density are predicted and compared to experiments. Subsequently, the work focused on investigating the consequences of these new loadings. We primarily show two effects: the first is swelling of about 10 to 15 % of the specimens observed through TEM studies, and the second is an "embrittlement" effect, with a reduction in the cohesive energy of 0.6 % to 20 % between the atoms of the target material depending on the theoretical model used

Full textThis work is divided into three main parts. Initially, in order to order to carry out our studies at smaller scales such as micrometric scale, we must not only use a more complex means of observation, for example, scanning electron microscope "MEB-FEG" to obtain images usable in metrology optical, but also have to mark (speckle) on these scales. More recently, digital image correlation is the most widely used kinematic field measurement technique to study the mechanical behavior of materials and structures over an area of interest ranging from the meter scale to the millimeter one. This can be obtained by using a dual-focused ion beam technique. Furthermore, we have adopted a scientific approach by first developing an artificial speckle, with an engraving depth of the order of 100 nanometers. We also relied on statistical tools such as the range of gray levels, autocorrelation, the number of passes and the variation of magnification, which were necessary to validate the marking and to generate better results.In the second part, we coupled the DIC by utilizing the scanning electron microscope and the focused ion beam as the labelling techniques. In order to build a controlled and reliable metrological solution to observe and quantify the movements and deformations of matter at these scales. Several tests have been carried out on two metals ; Steel 304l and Inconel 718, toensure the repeatability and reproducibility of the procedure. In these tests, we proposed to calculate the horizontal and vertical displacements as well as the error related to these displacements.We demonstrate the same approach on the deformation fields. Different results have been obtained depending on the variation of the standard deviation found in the acquired data making it possible to quantify measurement errors as well as repeatability and drift over time.The last part of the proposed work is about the adaptation of measurement methods to the particular mechanisms of deformation at different scales, such as the location of fractures and damage. To study mechanical behavior and taking into account local fractures, we extract the deformations of a fractured material using a displacement field measurement method. The proposed approach consists of extracting the residual deformations of the first local gradients of H-DIC, the least disturbed by the fractures. Various tests have been carried out to assess the validity of this proposed new approach. An application to study the mechanical behavior of a metallic composite (Al / ω -Al-Cu-Fe) is proposed. Particular exploitation of all the fields lies in the good separation of the deformation fields and the cracked part. A discussion on the comparison between a conventional DIC analysis and its extension is presented on the zones without and with fractures

Full textNanofluidics research is motivated both by intrinsic interest in the novel transport phenomena observable only at the (sub-)nanometric scale, and by applications including energy generation, desalination, macromolecular analysis, and microscopy. Two key considerations in the development of such technologies are 1) the control of nonlinear ionic transport and 2) the characterization of electrostatic, frictional, and other interactions of solid-liquid interfaces with bulk electrolyte solutions. In this manuscript, I develop a coherent theory of ion-selectivity and nonlinear ionic transport in nanopores & 1 nm in diameter, rationalizing previous experimental work and offering new routes in the development of desalination, energy generation, and other exotic functionalities. I then explore each of the above considerations separately. First, I explore the limits of continuum theory in rationalizing nonlinear coupled transport observed experimentally in ångströmetric channels, revealing the irrelevance of the Navier-Stokes description of the fluid dynamics at this scale and highlighting the role of the frictional characteristics of the confining material. Finally, I examine the surface-controlled modification of applied electric fields in scanning ion conductance microscopy, proposing a new approach for the imaging of surface charge that may substantially improve on the spatial resolution of current techniques

Full textLa construction d'un spectromètre de masse adapté nous a permis d'identifier les ions produits pour des pointes de natures différentes (W, Pt et Pd) et pour différents gaz (H2, H2O et mélange H2-H2O). La richesse des ions formés relève d'une physico-chimie à l'échelle nanométrique.
Un microscope à projection intégrant cette source a été construit. Des grandissements de 500 000 ont été obtenus avec une résolution de 3Å. Outre l'intérêt évident d'une telle microscopie, ceci démontre une taille de source virtuelle inférieure à 3Å pour la source d'ions ouvrant ainsi des perspectives intéressantes en optique ionique, en FIB par exemple.
