OBSERVATION OF SPATIAL-DISPERSION OF SURFACE-PLASMON MODE IN HREELS OF HEAVILY DOPED N-TYPE INAS(001)
A protective capping procedure has been used to prepare surfaces of MBE-grown InAs(001) for HREELS and photoemission studies. The comparison between photoemission and infrared transmission spectra demonstrates that at a bulk doping level of 8 × 1018 cm3, the Fermi level at the surface coincides with...
