| Abstract: | The energy distributions N(E) of secondary electrons emitted from GaP and InP samples bombarded with 40 keV Ar+ ions have been studied by a retarding potential method and an electronic derivation. The spectra show beyond an intensive peak developed at 2 eV, a detailed spectrum between 80 and 140 eV. The analysis of this spectrum reveales Auger electrons corresponding to L23(P) VV and L23MIV–V(Ga) V or L23(P) NIV-V(In) V] transitions; moreover, peaks due to plasmon excitations and d band excitations can be distinguished. |
