“…In addition to cluster emission during sputtering, in some specific experiments the emission of nanoparticles, which had been adsorbed to the surface of a substrate prior to bombardment, has been reported. In a series of experiments, Baranov and coworkers found that such emission occurs for a wide range of impact conditions; the most recent references include [17][18][19][20][21]. These authors investigated energy deposition by the projectile both in the nuclear stopping regime -for instance, impact of 72 keV Au 400 clusters or 200 keV Au 5 clusters -and in the electronic stopping regime, such as 1 GeV Pb ions or 30 MeV C 60 clusters.…”

Detailed experiments and theoretical calculations on electronic sputtering of Au thin films (5-200 nm) on a quartz substrate are performed, revealing unusually large electronic sputtering, dependent on the thickness of the films. The dependence of electronic thermal conductivity (κe), electron-phonon coupling factor (g), and lattice thermal conductivity (κa) on the effective electron mean free path is taken into account in the thermal spike calculation for nanodimensional systems to elucidate the combined effect of the thickness and grain size on the electronic sputtering yield. The thermal spike simulation with refined parameters for nanodimensional systems gives a better explanation of the electronic sputtering process with a very good correlation between the experimental and theoretical yields than that of the thermal spike model with bulk parameters.
