The formation of the ordered surface structures upon successive deposition of Al and Sb onto the Si(100), Si(111), and Si(110) surfaces held at about 650°C were studied by low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES). The primary emphasis was given to the investigation of the formation of (Al, Sb)/Si interface at total coverages of adsorbates in submonolayer range. In this case, according to AES data the adsorption of Al and Sb atoms proceeds collaterally in a simple additive manner. In the LEED observations, several new reconstructions, Si (100)c(4×4), Si (100)2×8, Si(100)2×6, Si(111)2×2, [Formula: see text], and Si (110)3×4 which indicate the formation of the joint (Al, Sb)/Si surface phases were found. The conditions for the formation of the surface structures were summarized in the formation diagrams.
