PhD Position for the integration of microbatteries on flexible substrates
Mines de Saint Etienne, Gardanne
Centre Microélectronique de Provence
Materials Science Engineering 
Full Description:

Study Subject: Conformable microbatteries for autonomous systems


Host Research Centre: “Ecole des Mines de Saint-Etienne” (EMSE) is one of the French "Grandes Ecoles" dedicated to training highly qualified engineers. It is composed of five Research and Education Centres including the Microelectronics Centre of Provence (CMP). The CMP has adopted a policy of strong partnerships with the smartcard industry as well as several innovative SMEs. Research is organized in four departments covering domains of semiconductor manufacturing and logistics, digital security, as well as emerging fields of bioelectronics, flexible and printed electronics.
The flexible electronics research department (PS2) of CMP develops technological and scientific knowledge in the field of printed electronics. The department has a strong knowledge in the field of material and interface, electrical and mechanical characterization. The activities of the department are regrouped in the 660m2-area platform. This technological platform regroups facilities and technological equipment for R&D activities in micropackaging, micro and nano-electronics, in a clean room of 220m² 1000-class and 400m² 10000-class. The department is well-equipped for thin film processing by i) vacuum sublimation, and ii) solution and inkjet printing deposition techniques. Electrical characterizations are realized thanks to automatic probes stations and multiple testers. SEM, AFM, EBSD, X-rays, Nanoindentation, Raman spectroscopy and acoustic scanning microscopy associated with complete the analysis and device characterization.

Description of the position: The PhD student will aim to develop a new generation of lithium-ion microbatteries directly integrated on flexible substrates. Their direct application will be of great importance for Connected Objects of the “Internet of Things” (IoT), including wearable electronics among others applications. Breaking away from the classical assembly of technology building blocks, the microbaterry conception will be directly implemented on the flexible substrate through bottom-up technics.
This microbattery will be constituted of a nanostructured anode (self-organized TiO2 nanotubes conceived from the anodization of a thin Ti film deposited on PDMS substrate), a polymer electrolyte homogenously electrodeposited onto the nanotubes surface, and a high potential cathode.
The microbattery prototyping and development require additional skills in flexible electronics and electrochemical preparation of nanomaterials. The physico-chemical characterization of the microbattery components and the study of its performance under mechanical stress will investigated through microscopic, spectroscopic, and electrochemical technics.

Scholarship Description: The successful candidate should have a Master in material science, or microelectronic engineering. Strong collaboration spirit and good communication skills in oral and written English is mandatory, as publications in peer-reviewed journals and presentation in international conferences are needed. Good experimental skills will also be required.
The PhD position is for three years and start as soon as possible.
