HRTEM and MD re-examine atomic suspended chains

Publicado em 04/03/2011 – NanoTechWeb.org, em 01/03/2011 Since the discovery of gold LACs, different groups have observed the existence of significantly long interatomic Au–Au distances, 3.6–5.0 Å, in comparison with 2.9 Å in bulk gold. Controversial topic The origin of these long interatomic distances has been highly controversial, being attributed to the existence of light impurity atoms (contaminants) inserted […]
