The adsorption of atomic hydrogen on Si(112) has been investigated using scanning tunneling microscopy. The clean (112) surface is reconstructed into quasiperiodic nanofacets [each composed of a (111) and (337) terrace], and we find that atomic hydrogen does not remove this nanofacet structure at room temperature or 430 °C. This result demonstrates the surprising stability of the facet reconstruction.
