The insertion of lithium atoms in the channels of the single-wall carbon nanotube (SWNT) bundles is investigated using an ab initio calculation. The relaxed structure as well as the electronic band structure were obtained. Results reveals that Li insertion modifies the band structure by shifting the Fermi level to a higher density of states region, and this shift scales with the rate of insertion...
The possibility of inserting lithium into single wall carbon nanotube bundles during the growth process is analyzed in this work by using the Raman technique as probe. The nanotubes were prepared by the arc discharge method by using catalysts prepared by mixing compounds containing lithium and as their counterpart, a similar mixture without this alkali-metal. The two pair of samples studied in this...
