Molecular dynamics simulations were made of adatom diffusion on strained (111) Lennard-Jones surfaces. The strain influence on the diffusion parameter, D, was due to variations in the pre-factor alone. No strain dependence of the energy barrier was observed. In view of previous work, the results suggested that analyzing trajectories was superior to other theoretical methods when conclusions about trends in D were to be drawn.
