With the Helium-3 spin echo technique (3HeSE) surface diffusion processes can be directly observed at their characteristic length scales (nm) and time scales (ps). A coplanar monolayer of pentacene chemisorped on Cu(110) was used as a well characterized organic surface on which isolated pentacene molecules diffuse. To extract the different processes that contribute to the diffusion, we use molecular dynamics simulations to compare to and reproduce key features of the experimental results.
