Development of a Multidimensional Hydrodynamic-Radiative Model for Tin Plasmas in EUV Sources

This PhD position at the Institut national de la recherche scientifique (INRS) focuses on advancing computational physics to enhance EUV emission efficiency from tin plasmas. The project aims to create a 2D hydrodynamic-radiative model to simulate laser-tin interactions, accounting for laser absorption, plasma expansion, and EUV emission processes. The successful candidate will use experimental data to validate the model, contributing to the development of more efficient, compact, and robust EUV sources critical for semiconductor nanolithography. The work involves interdisciplinary collaboration between physics, computational modeling, and experimental validation, offering a unique opportunity to bridge theory and application in photonics and nanotechnology.

• Develop a 2D hydrodynamic-radiative model to simulate laser-tin plasma interactions for EUV emission at 13.5 nm.
• Integrate experimental parameters into the model to predict plasma dynamics and EUV yield.
• Validate the model using spectroscopic and yield data from tin plasma experiments.
• Analyze the influence of laser parameters (wavelength, pulse duration, time structure) on plasma efficiency.
• Collaborate with experimental teams to refine model inputs and outputs for practical applications.
• Publish findings in peer-reviewed journals and present results at international conferences.
