1. N th is the carrier density at threshold and is given by 2. A system thus cools slower, the higher the carrier density is. 3. A reduced carrier density means that the drift behavior of the carriers. 4. Due to problems with charge carrier densities via doping in zinc oxide. 5. The kinetic inductance increases as the carrier density decreases. 6. Near zero carrier density graphene exhibits positive photoconductivity and negative photoconductivity at high carrier density. 7. Near zero carrier density graphene exhibits positive photoconductivity and negative photoconductivity at high carrier density . 8. The equilibrium carrier density that results from the balance of these interactions is predicted by thermodynamics. 9. In a normal metal wire, the resistivity also increases as the carrier density n decreases. 10. Careful choice of the materials and alloy compositions allow control of the carrier densities within the 2DEG.
