Arrhenius Plot for Determining Diffusion Activation Energy and Prefactor

Figure 7 of

Tracking

According to the Arrhenius relation R=ve^-ED^/KT for any simple thermally activated process. By observing hop rates at several temperatures we are able to determine values for both the activation energy, E_D, and the attempt frequency , v. Note: at low temperatures the tip induced diffusion rate becomes significant; this is responsible for the large diffusion rate observed at room temperature.
