Large, free-carrier-induced, optical nonlinearities are observed in n-Si:P near the metal-insulator transition. X(3) varies superlinearly with n, suggesting an impurity interaction mechanism. A theory of the effect shows that it measures the pile-up of electron density at the impurities. The experiments imply that the pile-up varies rapidly with electron energy near the transition.
