✦ Synopsis

Atomic and electronic structures of the SrTiO 3 (1 0 0) surface have been studied by using scanning tunneling microscopy (STM). We observed the c(4 • 2) (h ¼ 0:25) phase and the series of the structural phase transitions, e.g., c(2

For the SrTiO 3 (1 0 0) surface reconstructions, Sr adatom model, consisting of ordered Sr adatoms at the oxygen fourfold sites of a TiO 2 -terminated layer, can explain the experimental results very well. We theoretically simulated the model clusters with the first-principles total-energy calculation. Calculated density of states and images for STM are in good agreement with the experimental results.
