Quasiperiodic Nanoscale Faceting of High-Index Si Surfaces

Abstract

Scanning tunneling microscopy reveals that Si(112) reconstructs into quasiperiodic, nanometer-scale facets. Each sawtoothlike facet consists of a single unit cell wide reconstructed (111) terrace (7 X 7 or 5 X 5) opposed by a 60 to 110 Argon wide (337) terrace. Nanofacets with a similar structure are also observed on Si(335), indicating that they are a general phenomenon for some range of vicinality towards [112]. The dimensions of these nanofacets suggest that Si(112) and Si(335) would be interesting substrates for the growth of corrugated superlattices.
