Dear All,
I have never performed the conductance calculations earlier, and have just read the Kwant manual. I quite understood theĀ  defining of left,right leads and the scattering region. But I could not find anywhere how to add the atomic number details of the atoms used in leads, and the scattering region.
Could somebody help me in this? The conductivity would depend on the lattice type, atom type etc. right?

Regards,
