Hey.
I want to derive the conductivity of graphene.
I'm looking for a formula of the sort:
[tex]J = \frac{e}{\hbar} n \frac{dE}{dk} D(E) \Delta E[/tex]
where
[tex]\frac{1}{\hbar} \frac{dE}{dk}[/tex]
is the electron velocity,
[tex]D(E) = \frac{dN}{dE}[/tex]
is the density of states,
[tex]\Delta E[/tex]
might be the applied voltage.
[tex]n[/tex]
is the free electron density,
[tex]J[/tex]
is the current density and
[tex]e[/tex] is the electron charge.
Thanks,
Remy.
