Research Associate / PhD Candidate in Silicon Crystal Growth Simulation

This shared PhD position is jointly offered by the German Center for Astrophysics (DZA) and the Leibniz-Institute for Crystal Growth (IKZ). The successful candidate will focus on numerical simulation, process scale-up, and optimization of silicon crystal growth under magnetic fields for future gravitational-wave detectors like the Einstein Telescope. The role combines advanced Computational Fluid Dynamics (CFD), heat transfer, and machine learning methodologies. The researcher will be employed by DZA and primarily conduct research at IKZ in Berlin under joint supervision.

• Develop and apply numerical models for silicon crystal growth processes operating under magnetic fields.
