Abstract
Early stages of growth of two-dimensional bimetallic Ag-In islands on the Si(100)-(2 x 1) surface were studied by means of scanning tunneling microscopy. Mixing the two different metals, one forms 1D chains on the Si (100)-(2 x 1) surface and the other one creates 2D islands, results in anisotropic 2D lattice structures formed of indium chains connected by perpendicular silver chains.
Growth at elevated temperatures results in more ordered structures. A model of the observed bimetallic structures and a growth scenario based on experimental data are proposed.
