**Context**

**PhD’s objectives**

Nanocomposite thin films will be elaborated and structurally characterized at IMN. The main objectives of the PhD work is to identify the influence of nanostructuration (nanoparticles, interfaces properties, nanoparticles dispersion ) on dielectric properties of nanocomposite/nanostructured thin dielectric layers.

To reach this goal nanocomposites and multilayers samples will be characterized and modelled. The main objectives of the Phd are the following:

- Nanoscale electrical characterization of the different materials elaborated at IMN, by atomic force microscopy (AFM): current by conductive AFM (CAFM), dielectric permittivity by Electrostatic Force Microscopy (EFM) and charges by Kelvin Probe Force Microscopy (KPFM)
- Macroscale electrical characterization by current and capacitance versus voltage characteristics and dielectric spectroscopy
- Finite element modelling of electrical properties of nanocomposites and multilayers thin film to understand the influence of nanostructuration (nanoparticles vs layer) and interfaces on the overall macroscopic properties

Le Laboratoire Plasma et Conversion d’Energie est une Unité Mixte de Recherche du Centre National de la Recherche Scientifique (CNRS), de l’Institut National Polytechnique de Toulouse (INPT) et de l’Université Toulouse 3-Paul Sabatier (UPS).

Les travaux de thèse seront réalisés au sein de l'équipe Diélectrique Solide et Fiabilité (DSF). Les activités de l’équipe concernent en premier lieu la fiabilité des systèmes isolés. Les travaux ont pour objectif la compréhension des mécanismes de génération et de transport de charges dans les isolants, ainsi que l’identification des processus conduisant au vieillissement et à la rupture de matériaux compte tenu des contraintes fonctionnelles rencontrées dans les dispositifs. Pour cela, des techniques de caractérisation originales sont mises en œuvre et l’on s’appuie sur une simulation numérique des phénomènes de transport.
