摘要：
We present molecular dynamics simulations of adatom diffusion on strained (111) Lennard-Jones surfaces. The strain influence on the diffusion parameter D is due to variations in the prefactor alone. No strain dependence of the energy barrier was observed. In view of previous publications, our results suggest that analyzing trajectories is superior to other theoretical methods when conclusions about trends in D are to be made.
