Fermi surface and quantum Hall effect of graphene

Hi all,

I am doing a research on grafene's properties. Unfortunantly, I have no basis to clearly analize the Fermi surface and quantum Hall effect of graphene.
I was hopping if something could explain me the second paragraph of the third page regaring the document linked at the bottom of this thread (as well as figure 2 and 4).

Thank you for your attention

Happy new year

heh... I can barely spell my own name.. That stuff is beyond me.

Rather interesting stuff though.. Graphene transistors are mighty cool. Cant wait until we can get ahold oh them.

I too am not a Noble Prize winner. No help here!

Hmm, Phonons, Klein tunneling, Dirac eqns for massless fermions, 2D Fermions.

I daresay I didn't meet this stuff in Highschool, nor Engineering.

PhD material.

Last Klein I encountered was a pliers....

!! LOL!!

Now thats funny.

I have quite a few Klein tools. Now I can talk about them all day.
