Abstract

Hyper Raman Scattering (HRS) is considered as a convenient tool of studying the interface region of the metal- semiconductor contact. The effect of the band bending near the interface results sometimes in an accumulation of free carriers near the interface. The strong inhomogeneity is shown to induce local changes of the sign of the dielectric permittivity and in the consequent strong enhancement of the HRS intensity. The application of a bias potential is shown to govern the enhancement process.
