Diffusion at Surfaces: Introductory Remarks
As a motto for this introduction to the chapter on surface diffusion, I have chosen the very last sentence of Einstein’s famous and incisive paper  in which he relates the coefficient of diffusion to the (root mean square) displacement of a particle and the time elapsed between the initial and the final observation. Even he, Albert Einstein, asks for experimental confirmation of his deductions. Since the three contributions here are experimental observations and measurements, it seems that Einstein’s hope is being fulfilled.
