11. So the carrier density eventually falls back to below lasing threshold which results in the termination of the optical output. 12. Charge carrier density is a integrating it over a volume V gives the number of charge carriers N in that volume 13. In a material at thermal equilibrium generation and recombination are balanced, so that the net charge carrier density remains constant. 14. I did a Hall analysis on it and found 0 carrier density at positive 0.2 volts on the gate. 15. When the carrier density exceeds that value, the ensuing stimulated emission results in the generation of a large number of photons. 16. In the first hundreds of femtoseconds, the carriers are scattered by phonons, or at elevated carrier densities via Coulomb-interaction. 17. The carrier density is depleted during the pulse, and subsequently rises due to continued current injection, producing a smaller secondary pulse. 18. Scattering by graphene's acoustic phonons intrinsically limits room temperature mobility to at a carrier density of, times greater than copper. 19. Despite zero carrier density near the Dirac points, graphene exhibits a minimum conductivity on the order of 4e ^ 2 / h. 20. To make an accurate prediction of the exact position and shape at elevated carrier densities , one must resort to the full SLEs.
