K. Kempa et al., CORRELATIONAL SWITCHING BETWEEN 3X1 AND 6X1 SURFACE RECONSTRUCTIONS ON SI(111) WITH SUBMONOLAYER AG ADSORPTION, Physica. B, Condensed matter, 230, 1997, pp. 800-802
Electron correlations are strongly enhanced in low-dimensional systems
. Taking correlations as the dominant mechanism, we provide an explana
tion of the recently observed electrostatically enforced structural ph
ase transition(3 x 1 to 6 x 1) on a Si(1 1 1) surface with submonolaye
r Ag adsorption.
