“…Surface modification of materials by incident ions has been observed using electron microscopy, scanning tunneling microscopy ͑STM͒, and atomic forces microscopy ͑AFM͒. [1][2][3][4] A large variety of features have been studied: hillocks, 5 depressions, [6][7][8][9] crater rims, [1][2][3]10 adatoms, [11][12][13][14] and surface roughening. 15 Hillocks can appear when an energetic process occurs a few layers below the surface.…”

Cratering-energy regimes: From linear collision cascades to heat spikes to macroscopic impacts

Using classical molecular-dynamics simulations we examine the formation of craters during 0.4-100-keV Xe bombardment of Au. Our simulation results, and comparison with experiments and simulations of other groups, are used to examine to what extent analytical models can be used to predict the size and properties of craters. We do not obtain a fully predictive analytical model ͑with no fitting parameters͒ for the cratering probability, because of the difficulty in predicting the probability of cascades splitting into subcascades, and the relation of the heat spike lifetime and energy density. We do, however, demonstrate that the dependence of the crater size on the incident ion energy can be well understood qualitatively in terms of the lifetime of the heat spike and the cohesive energy of the material. We also show that a simple energy density criterion cannot be used to predict cratering in a wide ion energy range because of the important role of the heat spike lifetime in high-energy cascades. The cohesive energy dependence differs from that obtained for macroscopic cratering ͑observed, e.g., in astrophysics͒ because of the crucial role of melting in the development of heat spikes.
