Ion energy-angle distribution
Web29 okt. 2024 · The energy- and angle-resolved distributions of the ions at the grounded electrode, F(ε, Θ), show small differences when the number of harmonics is changed, as illustrated in figure 21 for the case of 20 Pa pressure. The peaks in the IFEDF become less pronounced when the number of excitation harmonics is increased.
