Density of states

    1. The problem statement, all variables and given/known data

    Using the dispersion relation at the Dirac Point calculate the electron density of states for graphene in both the valence and conduction band.

    2. Relevant equations

    ρ = density of states = k2/pi2

    3. The attempt at a solution

    I looked up what Dirac Points actually are, "which are defined as the contact points between the two bands." I have been unable to determine how to relate that to the density of states equations I have.
