The electronic stopping powers and angular energy-loss dependence of helium and lithium ions in the silicon crystal
Original language description
We have measured the electronic stopping powers of helium and lithium ions in the channelling direction of the Si < 100 > crystal. The energy range used (2.0-8.0 MeV) was changed by 200 and 400-keV steps. The ratio a between the channelling and random stopping powers was determined as a function of the angle for 2, 3 and 4 MeV He-4(+) ions and for 3 and 6 MeV Li-7(+.2+) ions. The measurements were carried out using the Rutherford backscattering spectrometry in the channelling mode (RBS-C) in a silicon-on-insulator material. The experimental channelling stopping-power values measured in the channelling direction were then discussed in the frame of the random energy stopping predictions calculated using SRIM-2013 code and the theoretical unitary convolution approximation (UCA) model. The experimental channelling stopping-power values decrease with increasing ion energy. The stopping-power difference between channelled and randomly moving ions increases with the enhanced initial ion energy. The ratio between the channelling and random ion stopping powers alpha as a function of the ion beam incoming angle for 2, 3 and 4 MeV He+ ions and for 3 and 6 MeV Li+.2+ ions was observed in the range 0.5-1.
