Dark Rate = X events/second
Dark Rate = Probability of occurrence * Volume of Sensitive region * Density of Valence Electrons * Rate of Scattering
Dark Rate = * 0.0033 mm^3 * 200 pixels * 2.329g/1000mm^3 * 6.022*10^23molecules/28g *
thin depletion region (0.7-0.8 um)
Make sure to do it in pixels
Mean velocity of valence elctrons = Fermi Velocity
Fermi Velocity = Fermi momentum / Mass of electron
