Energy-band diagram of 2D graphene

[serhan]

Hi,

I followed the graphene tutorial. I get the E-k diagram shown with Fig. 6 in the tutorial. However, I could not reproduce the 2-D dispersion relation (Fig. 7). How can I get Fig. 7 from Fig. 6? Or will I get the E-k values from the command prompt and then plot it in MATLAB etc?

Cheers

That's one possibility, or you can use the Matplotlib/Pylab plotting engine in ATK to do the plot, as I did for the tutorial. I'll post some scripts later!

Thanks again
