Abstract

Possibilities of the nucleation of nanoislands in surface thermal spikes caused by swift highly charged ions are investigated in this paper. Nanoislands may occur when the characteristic time of the nucleation becomes shorter than that of the spike cooling down. The values of system parameters favorable for the nucleation are estimated. The region, where the maximum nucleation rates are possible, can be shifted from the spike center. That can result in appearance of a ring-shape distribution of nucleated nanoislands in the vicinity of the projectile inlets.
