Hi

I am using vasp for calculating the bandstructures of nanowires.
Can anyone help me to figure out the parameters to be given in
input files KPOINTS and INCAR.How should the k-point file be
to do the bandstruture calulations if i had to move from (gamma)
point to x point.

What are you nanowires? How to configure ?

use an Nx1x1 k-mesh (N for the direction in which the wire is periodically repeated).

When calculating bandstructures, we are required to use k points along high symmetry lines. Anyone has any idea what are those k points for nanowires?

Thanks.

I'd suggest getting a good grip as to why you're calculating the bandstructure, and what the physical significance of the bandstructure is. Then I suspect you'll be able to answer your own question.
