ON THE METALLICITY OF SOME CARBON NANOTUBES

ON THE METALLICITY OF SOME CARBON NANOTUBES

Some zigzag and all armchair single-walled carbon nanotubes are believed to behave as metals. However, recent experimental results suggest that only armchair single-walled carbon nanotubes show typically metallic behavior. It has been suggested that metallic zigzag nanotubes are not true metals but...
