Jonas, What do you mean by "MKL libraries"? Supposing you are trying to compile Siesta 3.0, check the directory Src/Sys. It has many examples of arch.make files which you can use directly or adapt, if necessary. Also, do a search in the list archives - loads of arch.make's have been posted in the

Ian, I guess what Andrei meant is that your cell should be, in the limit, infinite along the z direction. I would guess that when he speaks of layers, it is related to the length of the z axis in units of layer thickness. In the limit of infinite z-axis length, your BZ will be 2-dimensional and al

Thanks for the reply. Taking the limit of what you've said, Andrei - if you want a really slow dispersion in the k_z direction, it would presumably be best to work with a thin (i.e zero thickness) slab. This would mean the dispersion in the k_z direction should be infinitely slow - right? This is

Hi Jan First of all, you have to build a supercell without vacuum, for your surface ... so you have a redundant definition for your bulk, but one with machtes with your surface cell. Of course you dont need as many atomic layers as for the slab case ... Second, you must calculate the band-structe

SIESTA is capable of your (computationally intensive) problem. When working with metals, be sure to use a large MeshCutoff ( > 350 Ry.) as well of plenty of k-points. If you have a lot of k-points, then you can use the Diag.ParallelOverK option. Daniel J. Backlund Texas Tech University - Phys
