Ca. Ventrice et al., STABLE RECONSTRUCTION OF THE POLAR (111) SURFACE OF NIO ON AU(111), Physical review. B, Condensed matter, 49(8), 1994, pp. 5773-5776
Several theoretical studies of the stability of (111)-terminated ionic
crystals with the NaCl structure have predicted that the crystal Made
lung energy can be stabilized by a simple surface reconstruction. Howe
ver, previous attempts to grow (111)-terminated crystals have resulted
in either unreconstructed or faceted surfaces. We demonstrate that de
position of Ni in an oxygen atmosphere onto a Au(111) substrate held a
t T approximately 300-degrees-C results in the growth of a stable p(2
X 2) reconstructed NiO(111) and resolve the atomic details of this sur
face with our scanning tunneling microscope.
