abstract (eng):

Presenting a computer simulation of low-energy electronic excitations that are created in atomic collision cascades initiated by the impact of energetic particles onto a solid surface. The electron-hole pair excitation energy is assumed to spread around the point of original excitation with a diffusion coefficient D. It is shown that for reasonable values of D the electronic energy deposited at the surface can be substantial, thus leading to transient electronic surface temperatures reaching thousands of K.
