Step Motion on Crystal Surfaces. II

Schwoebel, Richard L.·1969·Journal of Applied Physics

Abstract

A theory for step motion on crystal surfaces undergoing growth, evaporation, and annealing is described. The capture and detachment of atoms at surface steps is considered to occur with arbitrary probability. It is shown that differences in the capture and/or detachment probabilities lead to important characteristics of the step motion. Surfaces with sinusoidally distributed steps will smooth or roughen during growth or evaporation in the same manner as predicted by macroscopic capillarity theory. The conditions under which the kinetic and quasiequilibrium considerations apply are given in terms of the capture and detachment rate constants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
