Dear Shakerzadseh,
Please pay attention to the follow keys

MeshCutoff    100.000000 Ry -> larger 300.00 Ry
MaxSCFIterations    50 -> 100  or in your calculation the scf is converged
or not?
DM.NumberPulay    0   -> 5 or larger
DM.MixingWeight    0.250000 # can be varied, to be smaller, like 0.1

Another question is that you need PBC. In your case, it is molecule. This is
not the case.

Add
%block LatticeVectors
%endblock LatticeVectors
according to your case which should 1D period nanowire. Also K-point is
important.
