Controlled growth of thin films on highly reactive silicon surfaces has been a challenge for decades. High density of surface dangling bonds, however, hinders the adsorbate diffusion and its self-organization. In our work, we propose a novel use of t

Surface diffusion is one of the basic processes determining morphology of a growing film. In the case of metal heteroepitaxy on Si(111)-(7X7) the diffusion is strongly affected by the presence of surface reconstruction, which introduces additional co

Initial stages of Ag on Si(111)−(7 × 7) surface nucleation were studied at submonolayer coverage. Samples were prepared by thermal evaporation of Ag from tungsten wire under UHV conditions (p

Gold films were thermally evaporated in vacuum on heated cleaved mica substrates. The substrate temperature was immediately decreased after finishing the growth. Samples prepared at various temperatures from 580 K to 890 K and evaporation rates small

Metallic surface with an ultrathin oxide layer can be used as a substrate for STM study of small metal particles. The polycrystalline nickel film with a natural oxide layer was tested for STM observations under air conditions. Influences of a substra

Scanning tunneling microscopy (STM) was used for studying nucleation and growth of 1-dimensional indium islands (chains) at coverage below 0.5 ML on the reconstructed Si(100)2×1 surface at room temperature (RT). In-vivo measurements - direct observa
