Abstract
Emission of secondary C+ ions from the surface of well-oriented graphite nanocrystallites irradiated with 10 keV Ar+ ions has been studied. The energy distribution of emitted secondary ions has been measured. It has been found that the form of energy distribution and the energy corresponding to the maximum of distribution Emax depend on the polar angle θ of C+ ion emission. The linear dependence of energy in the maximum of energy spectrum of single-charged secondar y carbon ions on the polar angle of their emission Emax(θ) has been obtained. The mechanism responsible for the observed features of the energy spectra is discussed.
