Problem 4 - Diffusion on Surfaces - the use of original literature (publications) is not permitted for this problem - 20 points (15/5) (a) The figure shows the position of adatoms measured with a special atom-tracking STM. What is the activation energy for the atom diffusion on this surface? Assume v0=1012s1. (15 points) (b) How (and why) does the surface structure influence diffusion?
