How to Plot a 2D band structure? [Solved]
Dear DrDu and Wolfgang2b,
Thank you very much. Your answer was very useful. It worked pretty fine. Now I'm able to plot the 2D and 3D for graphene on matlab.
For 3D plot, I had to use meshgrid(), in order to create the matrix KX an KY, then use...
Dear forum people,
I just learned how to get a tight-binding dispersion for graphene:
E = +- \sqrt{1+4\cos((\sqrt{3}a/2) k_x)\cos((a/2) k_y)+4\cos^2((a/2) k_y)}
But i can not figure out how can I plot that. I want to plot that in the following path: K \rightarrow \Gamma \rightarrow M...
