INVESTIGATION OF SCATTERING Ar+ IONS FROM CdSe(001) SURFACE AT THE GLANCING INCIDENCE

In this paper, we present and discuss the energy distributions and characteristic trajectories of scattered Ar+ ions from the CdSe(001) surface at the angles of incidence ψ =3°, 5°, 7° and at the initial energy E0=3 and 5 keV. In the obtained energy spectra, two intense peaks are observed, which...
