Dear Sir,
    Yes, that will be the contour plot at the value E=0 (for both spin up and spin down). Please see the fig 6 inset as well as fig 7 in ref Phys. Rev. Lett. 101, 256801 (2008).  

Thanks
Ramkrishna

This is the kind of task which is very difficult to provide a single, simple script that works in all cases. At best I can show an example, but it may need modifications for particular systems etc.

I took Palladium and cleaved it 100. Then I calculated it selfconsistently with DFT-LDA. Then, I used the attached script to plot the band structure in the kx-ky plane and the contour lines show the Fermi level. I'm not sure the results are meaningful, but hopefully they will be for your more interesting system :)

Hi ,
Can someone tell me what does "Isolevel" signifies in XCrySDen during plotting of Fermi Surface ?

Thanks,

It most probably means the value of the Fermi energy on the Fermi surface.
