Electronic and optical properties of fullerene nanostructures

Two new types of molecular/electronic fullerene nanostructures are consider ed: 1) highly stable hydrated clusters (I-h symmetry group) and microcrysta ls (T-h symmetry group) of fullerene C-60 in water solution and 2) the sing le-walled carbon nanotube from C-60 fullerenes. The vibrational spectra of these fullerene nanostructures are calculated using molecular dynamics. The electronic properties of a single-walled fullerene nanotube are investigat ed using the tight-binding method. The theoretical results obtained were co mpared with available experimental data.
