Dear Pablo, I have no idea on graphene, so my suggestion is based on "common sense". Check what kind of impurity level/band nitrogen is forming, and if your half-integer occupation per spin comes from a too large dispersion of this band, it may be an artefact of not big enough supercell. Otherwise

Dear Siesta Users, I did some calculations for 4x4 graphene doped with nitrogen. when I was doing the optimization (cell parameters and atomic position) I found two solutions. One of the correspond has a net magnetic moment of 1 uB ( 65 spin up and 64 spin down).

Dear Fen, as you are using rho2xsf you probably got it along with the whole packed directory, which also contains the README file. It contains some minimal explanations. Looking at your output, I see two problems: 1. Your selected visualization box centered at (1, -2.3, 9) Ang and spanned by three

Dear all I want to check the charge density about the molecular adsorbed on the surface. When we use the rho2xsf , there is a lot of the choices,such like [...@linux]$ rho2xsf Specify SystemLabel (or 'siesta' if none): test Now define the grid cell for your XCrysDen plot. Note that it can be ar

Hello again, Some time ago I have post a message to the list about the problem with the SIESTA (built on IBM Power system) running out of luns. The original post is below. In the meantime I have contacted the system administrator, who helped me to identify the problem. Here is his response: th
