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.
