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.

Scanning Probe Microscopy: From Sublime to Ubiquitous
This collection marks the 35th anniversary of scanning tunneling microscopy (STM) and the 30th anniversary of atomic force microscopy (AFM). These papers, all published in the Physical Review journals, highlight the positive impact that STM and AFM have had, and continue to have, on physical science research. The papers included in the collection have been made free to read.
