Thermodynamic and kinetic characteristics of variations in shapes of ridges formed on {l_brace}100{r_brace} lithium fluoride surfaces
channels with widths in the range form 5 {mu}m were formed in {l_brace}100{r_brace} surfaces of LiF single crystals by a photolithographic technique. Specimens annealed at or above 0.90 T{mu}m, where T{mu} is the melting point, and then quenched showed the channels and the ridges between them develop rounded profiles. Evolution of these profiles was evaluated for the various channel widths and for interchannel ridge spacings of 5 to 100 {mu}m in terms of: (a) an accepted theoretical model for a surface diffusion controlled process, and (b) a model which assumes that shape changes depend only on the relative energies of attachment of atoms in surface sites with various surface curvatures. Either model is consistent with the experimental observations to within the reproducibility in measurements.
