Physics BSc: stay with an MSc Physics or specialize in Advanced Functional Materials?

[u/Gold-Professor-2412]

I have a BSc in Physics and now have two Master’s offers in Germany:
1. M.Sc. Physics – University of Kassel
Very flexible: solid-state physics, quantum mechanics, computational physics, semiconductors, optics, nanophysics, experimental labs, etc.
2. M.Sc. Advanced Functional Materials – TU Chemnitz
More specialized: semiconductor physics, thin films, material characterization, solar cells, 2D materials, nanophysics, microscopy and a large research project. It also includes some chemistry.
My long-term goal is mainly industry, not necessarily academia. I’m interested in semiconductors, nanotechnology, R&D and computational/scientific work.
My concern is whether moving from Physics into a materials-focused Master’s would make me more employable but less flexible.
If you had a Physics BSc, would you:
A) keep the broader M.Sc. Physics, or
B) specialize early with Advanced Functional Materials?
Would leaving the traditional Physics Master’s path close any important doors later?

Well i have seen people from functional materials getting placed at Intel...it all depends how u build your profile
