Abstract
The reflectivity of -type InSb has been measured in the far infrared. The doping of the samples was such that the free-carrier plasma frequency was near the LO mode frequency. The results suggest that samples with a sufficiently thick damage layer show effects due to surface plasmons. Use of a simple model indicates that the surface-plasma excitations are coupled to the phonons.
