Self-assembly of endohedral metallofullerenes: a decisive role of cooling gas and metal–carbon bonding

Qingming Deng、Thomas Heine、Stephan Irle 等 4 位作者2016-01-01Nanoscale

The endohedral metallofullerene (EMF) self-assembly process in Sc/carbon vapor in the presence and absence of an inert cooling gas (helium) is systematically investigated using quantum chemical molecular dynamics simulations. It is revealed that the presence of He atoms accelerates the formation of pentagons and hexag…
