The results are discussed in comparison to the “free” isomers of C80fullerenes andTi2 @C80 endofullerenes, as well as to all-carbon nanopeapods, i.e., C80 isomers inside a carbon nanotube (C80@C-NT). It is demonstrated that the type of Ti2@C80 isomer determines the energy effect of its encapsulation into the tube (exo- or endothermic), the orientational arrangement of endofullerenes in the tube, the charge states of the Ti2@C80 and tube atoms, and the electronic properties of nanopeapods (semiconducting or metallic) Полный текст |
