Dear Muthu V,
Still your system is cubic, is this what you want? After the relaxation
of the cell there are off-diagonal components in the stress tensor; this
might hint at a phase transition into a different kind of cell, but it has
not occurred duering your relaxation. There are no
Dear David,
If your structure is 2D and with some vacuum let say along Z, then you may be
looking for bands in the XY plane which you have periodicity. So your automatic
k-points should be look like: (kx ky 1) and for band structure you need to use
manual k-vectors and span the XY plane along
Dear Users
Suppose, we have constructed a metallic surface and a vacuum slab with some
thickness.
Normally, these super-cells have no symmetry. My main question is that how we
should
choose the k-point? Only in the surface or we can choose some points in the
inner layers
or even vacuum
Thank you

Thanks for help. I will try.
