“…This is due to the presence of a large number of interband transitions that overlap and interact with collective oscillations. 20 The stopping power and the energy-loss straggling of H + in Au calculated by the MELF-GOS method show a good agreement with available experimental data. 21,22 The interaction of the dissociated molecular constituents with the target nuclei, giving rise to multiple elastic scattering and nuclear energy loss, is included in the SEICS code through a Monte Carlo approach.…”

Influence of the description of the target energy‐loss function on the energy loss of swift projectiles

“…[30] The broad spectrum observed in Au is due to the presence of a large number of interband transitions that overlap and interact with collective oscillations. [31] It is then necessary to use seven Mermin-type ELFs to fit correctly the experimental ELF corresponding to the outer-shell excitations. On the other side, Al behaves as a free electron gas, and so, the optical ELF displays a single sharp peak at the plasmon energy; consequently, the optical ELF was fitted by a single Mermin function.…”

The atomic and electronic structures of NiO(001)/Au(001) interfaces

“…Then a Au(001) thin film with thickness of ∼10 atomic layer was epitaxially grown at room temperature (RT) on the Ag(001) substrate at a deposition rate of 0. 35 0.39 ML/min in O 2 atmosphere (1 × 10 −6 Torr) at RT. The thickness ranged from 1 up to 10 mono-layer (ML: 1 ML = 2.30 × 10 15 atoms/cm 2 : areal density of NiO(001), 1.20 × 10 15 atoms/cm 2 for Au(001)) and the crystalline quality was checked by reflection high energy electron diffraction (RHEED).…”
