Offer Description

The researcher (M/F) will work within the framework of the ANR Lamorsim project (https://anr.fr/Project-ANR-23-CE08-0029 ). The main objective of this project is to develop methodologies for achieving controlled laser-induced amorphization of silicon.

In this work, the researcher will develop experimental configurations to induce and study the transformation of silicon. The work includes pump–probe reflectivity measurements to investigate the melting and solidification dynamics of crystalline silicon under femtosecond laser irradiation. The aim is to understand the conditions most favorable for the direct formation of amorphous layers, which are of great interest for new applications in microelectronics (silicidation for electrical contacts) and photonics (waveguide writing).

The researcher will also be responsible for implementing beam-shaping techniques to produce uniform layers, as well as exploring the possibility of generating micrometric amorphized volumes inside silicon, thereby opening new application areas.

The results of these ultrafast optics experiments will contribute to a better understanding of surface annealing processes, with the goal of achieving optimized control over the final material state, taking into account its crystalline structure as well as the location and depth of the transformations.

He or she shall contribute to activities such as:

• Experimental analysis and/or modeling of the interactions and material responses
• performance optimization of laser writing processes (Process engineering) and technological demonstrations
• participation in the implementation of new interaction strategies and new optical diagnostics
• publication of one or more articles on the analyses of the data collected during the project.

Located in the Luminy Campus in Marseille, the Lasers, Plasmas and Photonic Processes (LP3) laboratory was founded in 2000. It is a Joint Research Unit (UMR 7341) of CNRS and Aix-Marseille University (AMU). The research of LP3 laboratory is focused on laser matter interaction in short and ultrashort temporal regimes. Studies address fundamental mechanisms induced when a pulsed laser beam interacts with matter, in order to manage the physical phenomena that control the effects of the interaction and then to develop innovative photonic processes.

We are looking for a highly motivated and independent scientist (M/F) interested in laser science and technologies, ultrafast optics and/or material processing. Applicants should have demonstrated expertise in laser process engineering and beam shaping technologies (Beam transport and manipulations, synchronizations, motion control, scanner operation, …). Excellent spoken and written English is mandatory.
