Abstract
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 Li/SWNT band structure
allows to predict strongly modified electronic properties. (c) 2005
