2D In₂Se₃ Symmetry Engineer: Ferroelectricity & Phase Study

C2N, CNRS-Université Paris-Saclay; Palaiseau; On-site; EUR 13,000 - 17,000; Full time

Job summary

Symmetry engineering internship at C2N, CNRS-Université Paris-Saclay, focusing on two-dimensional In2Se3 semiconductors. The student will contribute to growth and characterization using CVD, Raman spectroscopy, and polarization-resolved SHG.

The project is part of RHOMBO2D (ANR) and offers pathways toward a PhD, with collaboration across C2N, MPQ, IPCMS and SPINTEC. Training will cover advanced materials synthesis, optical probing, and data analysis within a multi-institutional team.

Qualifications

• Experience with thin film growth or characterization preferred.
• Familiarity with micro-Raman spectroscopy and SHG measurements is advantageous.
• Willingness to learn and work in a collaborative research team.

Responsibilities

• Grow and characterize thin In2Se3 layers and identify their phase.
• Perform Raman spectroscopy and polarization-resolved SHG to probe symmetry.
• Compare α- and β-phase samples under varying thickness and post-growth annealing.
• Contribute to publication-ready results and potential PhD continuation within RHOMBO2D.
