摘要：

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 x 10(18)/cm3, the Fermi level at the surface coincides with that in the bulk. This allows observation of the effects of spatial dispersion in the surface plasmon mode in HREEL spectra.
