| Abstract: | In n-channel accumulation and inversion layers on the (110) and (111) surface of Si, inter-subband optical transitions can be induced by infrared light incident normal to the surface. The resonance screening and exciton-like effect depend strongly on the nature of the valley degeneracy in this configuration. Examples of numerical calculation of the absorption spectrum are presented. |
