Structural Transformations in Carbon Nanoparticles

摘要

The structure of icosahedral carbon (diamond and onion-like)nanoparticles is discussed.It is shown that,in carbon nanoparticles,the reversible structural transformations of icosahedral particles into particles with a shell structure can occur without breaking of bonds or disturbance of their topological integrity.New structural models are proposed and analyzed for carbon nanoparticles.The diffusionless mechanism of reversible transformations between diamond-like and onion-like particles is proposed for the first time.
