摘要：
The An adsorption induced root 21 x root 21 super-lattice structure on the Si(111)-root 3 x root 3-Ag structure has been investigated using reflection high-energy positron diffraction. The height of the Au adatom was determined to be 0.59 angstrom from the underlying Ag layer from the rocking curve analysis with the dynamical diffraction theory. The adatoms were preferentially situated at the center of the large Ag triangle of the inequivalent triangle structure of the Si(111)-root 3 x root 3-Ag substrate. From the intensity distribution in the fractional-order Lane zone, the in-plane coordinate of the An adatoms was obtained. (C) 2007 Elsevier B.V. All rights reserved.
