Surface Dynamics of Stepped Si(001) Studied by Temporal Leed Spectroscopy
- We present the first demonstration of Temporal LEED Spectroscopy’s ability to measure surface dynamics as shown by a study of step dynamics on vicinal Si(001). While we measure activation energies consistent with other work, the observed microscopic mechanism driving the fluctuations is inconsistent with previous claims. We exclude evaporation/condensation of atoms from the steps as the rate limiting kinetics in the temperature range of this experiment. Possible reasons for these differences are discussed.
