By using classical molecular dynamics technique we have simulated the effec
ts of 5 keV Xe atoms impinging on the strained Ge(1 0 0) 2 x 1 surface. We
found that large adatom islands are formed on top of the amorphous zones cr
eated by the cascades. We also found that lattice atoms around the molten z
one move radially inwards and thus cause strain relief in the sample. (C) 2
