Description of the thesis topic

The aim of this project is developing new fabrication processes for advanced miniaturized (bio)sensors that will be useful for human being monitoring. We propose a technology that is based on solution process and laser curing for micro and nanopatterning. Such process will be used to fabricate field effect transistors (FET) and photodetectors (PD) that will be used
for designing biosensors as end-product.
One of the main innovation relies on the amorphous metal oxides microstructures preparation. To achieve at the same time direct write process and suitable semi-conductor properties, we propose laser irradiation to prepare in situ, in one-step, at room temperature the semi-conducting micro-nano-structures.

Work Context

The Mulhouse Materials Science Institute (IS2M) is a CNRS-University mixed research unit located in Haute-Alsace (UMR 7361). Because of its multidisciplinary character, its scientific impact and the way it interacts with other fields, the laboratory represents one of the structuring forces in the field of Materials and their applications in the academic and industrial world, both at regional and national level. The IS2M has been able to define its identity and acquire unquestionable visibility on the highly competitive landscape of international research.
The general objective of the Institute is to advance the knowledge front and transmit expertise in the field of Surfaces and Interfaces, Functionalization and Porous Materials.
In particular, the Institute aims to be a major player in the development of innovative methods and processes of synthesis, formatting, functionalization and bio-functionalization, in the field of development of characterization methods (specific and/or tailor-made), in the study of interaction mechanisms between a surface and its environment and in the study of correlations of properties on different scales.
The project will be carried out in team PHOTON which develop and investigate micro and nanopatterning processes for functional materials.
