Due to their good mechanical properties combining elasticity and toughness, Diamond-Like Carbon (DLC) seem to be particularly well suited to this ultra-thin layer application as an active part of vibrating MEMS. The DLCs are an amorphous form of carbon material with two types of carbon atoms: sp2-hybridized with sigma and pi bonds as in graphite and graphene and sp3-hybridized with only sigma bonds as in diamond. The mixing of these two types of carbon atoms allows to tune the properties of the… Show more Due to their good mechanical properties combining elasticity and toughness, Diamond-Like Carbon (DLC) seem to be particularly well suited to this ultra-thin layer application as an active part of vibrating MEMS. The DLCs are an amorphous form of carbon material with two types of carbon atoms: sp2-hybridized with sigma and pi bonds as in graphite and graphene and sp3-hybridized with only sigma bonds as in diamond. The mixing of these two types of carbon atoms allows to tune the properties of the material. These properties can be adjusted from graphite-like (soft, flexible, electrically conductive) to diamond-like (hard, strong, electrically resistive). DLCs film at the micrometer scale are widely used especially for coatings because of their chemical inertness and their tribology.Now that the micro electronics field tend to become the mico and nano electronics studies of DLC at nano scale are needed. Indeed the tunability of theses materials can be of great interest in several application if a suitable elaboration road can be desined.The aim of this thesis is to validate the sputtering approach of the elaboration of DLC ultrathin film at the CEA-Leti clean room.

In situ X-ray microtomography is a non-destructive method for observing the microstructure of materials in 3D during a thermal or mechanical treatment with a resolution of a few microns. This technique been found to be a valuable tool for investigating the sintering of metal powders as it provides data on particle rearrangement, interparticle necking, pore size and shape, etc., at various times in the course of sintering (Fig. 1). However, the standard resolution is not sufficient for… Show more In situ X-ray microtomography is a non-destructive method for observing the microstructure of materials in 3D during a thermal or mechanical treatment with a resolution of a few microns. This technique been found to be a valuable tool for investigating the sintering of metal powders as it provides data on particle rearrangement, interparticle necking, pore size and shape, etc., at various times in the course of sintering (Fig. 1). However, the standard resolution is not sufficient for ceramic powders, whose particles generally have a size of 1 μm or below. A novel set-up has recently designed at the Grenoble synchrotron (ESRF), which provides 3D images with a resolution of 50/100 nm. SIMAP researchers will perform experiments with this set-up during 3 days in mid-November. Before, preliminary tests should be achieved in order to select the ceramic powders that will be used, as well as the sintering conditions. This investigation comprising powder preparation, sintering tests and microstructure observation by SEM will be the first part of the project. Next the students will contribute to the experiments at ESRF together with several SIMAP researchers. Afterwards, they will work on the building of 3D images from the data collected at ESRF and to the analysis of these images by using a dedicated software. Show less

This internship was focused on the influence of semiconductor thickness on Organic Thin-Film Transistors. Devices are fabricated with a Top Gate/Bottom Contact geometry on plastic substrates by printing techniques. Impact of the active semiconducting layer thickness on electrical characteristics and device parameters is discussed.

The Generation IV International Forum is searching for the future nuclear energy systems that have safety parameters and waste recycling in their process. In this context the Molten Salt Fast Reactor (MSFR) is considered as a encouraging proposition. This proposed reactor concept is based on the dissolution of the fissile material in an inorganic fluid which circulates from the reactor core to the heat exchanger and back.Molten fluorides are a promising solution as inorganic… Show more The Generation IV International Forum is searching for the future nuclear energy systems that have safety parameters and waste recycling in their process. In this context the Molten Salt Fast Reactor (MSFR) is considered as a encouraging proposition. This proposed reactor concept is based on the dissolution of the fissile material in an inorganic fluid which circulates from the reactor core to the heat exchanger and back.Molten fluorides are a promising solution as inorganic fluid. Unfortunately, due to their hygroscopyonly few data on pure compounds exist. Without data on this molten salt, it is impossible to predict the neutronic of the system. The aim of this project was to analyse the fluorides using a setup build in the SIMAP labs that allowed us to measure, by Knudsen method, the vapor pressure of various materials. Show less

This internship has been focused on the qualification of a new set up for ultrasonic pulverisation which has been used for deposit FTO thin films on glass substrate. Elaborations conditions will be studied in order to optimize the deposition protocol in order to optimize the samples (i.e. sheet resistance below 10 Ohm). These obtained thin films have been characterized in a morphological and microstructural aspect. Electrical properties will also be studied by 4-point probes method… Show more This internship has been focused on the qualification of a new set up for ultrasonic pulverisation which has been used for deposit FTO thin films on glass substrate.

The absorption of sunlight from silicon photovoltaic devices is limited by the inability of silicon to absorb photons with energies lower or much higher than its bandgap. Photons with lower energy than the bandgap do not excite electron-hole pairs, and those with much higher energy do but the excess energy is dissipated as heat. Rare-earth materials have interesting photoluminescence properties that have potential use as down- or up- conversion of the incident sun radiation in order… Show more The absorption of sunlight from silicon photovoltaic devices is limited by the inability of silicon to absorb photons with energies lower or much higher than its bandgap.

Rare-earth materials have interesting photoluminescence properties that have potential use as down- or up- conversion of the incident sun radiation in order to improve photovoltaic efficiency.Rare-earth(Yb, Tb, Te)-doped Titania (TiO2) thin films where grown by aerosol-assisted metal-oxide chemical vapor deposition under three different batches differing in temperature (490, 550 and 420 °C). After being exposed to annealing temperatures (600, 800 and 950 °C),the films were examined for their microstructure (SEM), composition (FTIR, EDX) crystallinity (XRD, Raman) and luminescence (Fluorescence Spectroscopy).The films exhibited interesting crystallization of flower-like structures on the surface and some of them exhibited useful fluorescent emissions.
