7 × 7 Reconstruction on Si(111) Resolved in Real Space
Abstract
The 7 × 7 reconstruction on Si(111) was observed in real space by scanning tunneling microscopy. The experiment strongly favors a modified adatom model with 12 adatoms per unit cell and an inhomogeneously relaxed underlying top layer. © 1983 The American Physical Society.
