Solid phase epitaxial growth of Si on SiSb surface phases for the formation of δ-doped layers and δiδi-superlattices

Abstract The SPE growth of Si on SiSb surface phases has been studied by LEED and AES techniques. The surface phases studied were the disordered Si(100)Sb and the ordered Si(111) 3 × 3 -Sb one. Both surface phases have an Sb coverage of about one monolayer. Structures with single δ-doped layers and a δiδi-superlattice have been grown. The structural perfection of the grown Si films has been characterized on the basis of LEED data. The peculiarities of the annealing behaviour of Si films thinner than 10 nm have been detected.

Effect of Si(100)-c(4 × 12)-Al and Si(111)-(5.55 × 5.55)-Cu reconstructions on the deposition of cobalt onto silicon surface

The use of surface reconstructions for modifying properties of single crystal silicon substrates with a view to the creation of new nanostructures is a promising direction in the development of nanotechnologies. Systems Si(100)-c(4 × 12)-Al and Si(111)-(5.55 × 5.55)-Cu occupy special positions among stable reconstructions of the silicon surface, which have been recently demonstrated to be promising templates. The adsorption of cobalt on these surfaces at various temperatures has been studied using scanning tunneling microscopy. The room-temperature deposition leads to the formation of a weakly ordered layer of metallic Co with retained initial reconstructions at the Co/Si interface. An increase in the temperature leads to the formation of faceted cobalt silicide islands on both reconstructed surfaces.

Studying the Surface Conductivity of a Thallium Bilayer on Si(111) Substrate after Adsorption of Lithium and Rubidium

Changes in the state of a thallium bilayer on Si(111) substrate, Si(111)6 × 6–Tl, after adsorption of lithium and rubidium were studied using low-energy electron-diffraction and four-point probe-conductivity measurements. New surface reconstructions 5 × 1 and
