##### A sample of n-type semiconductor is found to be an insulator at very low temperatures. As the temperature is raised, there comes a point at which the conductivity increases markedly, but after this point the conductivity remains pretty much constant as the temperature is raised further. At much higher temperatures, the conductivity starts to increase steadily, with no sign of it reaching a plateau. Explain these observations.
