摘要
The growth, diffusion, and coarsening of Si on Si (001) have been investigated with scanning tunneling microscopy (STM). A diffusion coefficient for Si has been determined. Anisotropy in the island shapes during epitaxy is shown to be principally a growth structure due to an anisotropic accommodation coefficient. Diffusional anisotropy is small. An ordered “diluted-dimer” structure is observed at low coverages and temperatures. © 1990, American Vacuum Society. All rights reserved.
