摘要：

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 (7×7 or 5×5) opposed by a 60 to 110 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 [1̄1̄2] The dimensions of these nanofacets suggest that Si(112) and Si(335) would be interesting substrates for the growth of corrugated superlattices. © 1995 The American Physical Society.
