Principal results  

"It has been found that Beryllium adsorption onto the heated Si(111) surface results in the formation of  Be-encapsulated Si nanotubes, as was predicted theoretically. [Nano Letters, 2004].

"Reversible phase transitions in low-dimensional structures were found and studied. [Physical Review B, 2005; Applied Surface Science, 2004; Physical Review B, 2006].

"Rashba-type spin splitting of metal surface states was found in the Au/Si(111) system [Scientific Reports, 2013]. Optical measurements have shown a tenfold increase in the intensity of second harmonic generation for the Si(111) 3x 3-(Au,In) surface [Applied Surface Science, 2012]. The novel mechanism of the interaction between surface magic clusters has been described [Physical Review Letters, 2011].

"Self-assembly of fullerene islands mediated by the moir? interference between an island and the underlying lattice has been studied. We have shown that this discovery suggests an unexplored tactic of engineering atomic scale moire magnifiers to facilitate the growth of monodisperse mesoscopic structures [Nature Communications, 2013].

"We have proposed a strategy to create spin-split metallic bands using a dense 2D alloy layer containing a metal with strong spin-orbit coupling and another metal to modify the surface reconstruction. The strategy provides a new paradigm for creating metallic surface state bands with various spin textures on silicon and therefore enhances the possibility to integrate fascinating and promising capabilities of spintronics with current semiconductor technology [Scientific Reports, 2013, 2014].
