Okay thanks. I'll try working it out on my own now.

Well I just did but it's a but too much for me. I just want a simple formula for 2D crystals like graphene.

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

Hi I'm a third year physics student currently working on my bachelorstage, and I have a differential equation I want to solve, but can't =). Given an planet with an atmosphere so thick relative to the planet radius, that gravitation in the atmosphere cannot be seen as a constant but decreases...
