I would start by putting in the correct mass for Si on line 26 of your input file. I might also suggest using a different pseudopotential depending on what properties you are looking at.

Subject: [Pw_forum] Convergence problem in Si slab structure
Dear QE users,
I'm trying to optimize a Silicon slab structure with 13 atomic layers in each slab (attached file), but so far I have no success in optimizing because of convergence problem in SCF cycle. Does any one know who I can fix the problem.
