Missions

The integration of miniaturized supercapacitors (also called micro-supercapacitors) on circuit chips has been the subject of intense research on the account of their excellent charge-discharge rate and long operating life time. However, a significant improvement of their areal energy density is needed for more challenging applications. An attractive approach to enhance the energy per surface area is to increase the areal capacitance of electrodes by relying on a conformal thin-film of hydrous ruthenium oxide (RuOx.nH2O, the active material) deposited by atomic layer deposition (ALD), followed by an electrochemical oxidation process, onto a highly porous current collector prepared via a dynamic template built with hydrogen bubbles.
Within a framework of an ERC project dealing with the development of 3D Micro-Supercapacitors, a postdoctoral position is available at LAAS-CNRS (Toulouse, France).

Activities

The candidate will:
- explore the ALD of different stoichiometry of RuOx and hydrated RuOx with oxygen or ozone co-reactants
- perform physicochemical and electrochemical characterizations of the deposited films on different substrates.
- realize a component or prototype.

Skills

We are looking for a candidate with:
- a strong background on ALD and electrochemistry (both compulsory).
- An experience in micro-fabrication in clean room would be appreciated but not required.
- The candidate should be fluent in English; written and spoken

Work Context

LAAS-CNRS (Laboratory of Analysis and Architecture of Systems) is a CNRS research unit located in Toulouse (France). It is made up of 577 people (researchers, ITAs and doctoral students) and 26 research groups spread over 8 scientific departments. It benefits from a 1600 m2 technology center in a clean room.

Constraints and risks

The candidate should be highly autonomous and able to work for a multidisciplinary project involving researchers and scholars from very different fields.
