-First take a look at the complete geometry in ''all.xyz'' using ''vmd''. As you can see, this is a much larger geometry than what we had before and would therefore take a lot longer to optimize. This is why some tricks are used in ''geo_opt.inp'': For the nanoribbon (''mol.xyz''), we use the Density Functional based Tight-Binding (DFTB) method instead of GPW and couple the systems together by Force Fields (''FIST''). Look at the CP2K input file ''geo_opt.inp'' to get an idea how that looks like and then run the simulation.+First take a look at the complete geometry in ''all.xyz'' using ''vmd''.

 Like with the geometry optimization in the previous examples, you now should have a file ''nanoribbon-geo_opt-pos-1.xyz''. Like with the geometry optimization in the previous examples, you now should have a file ''nanoribbon-geo_opt-pos-1.xyz''.
