The electronic properties of exohedrally doped double-walled carbon
nanotubes (DWNTs) have been investigated using density functional theory
and resonance Raman spectroscopy (RRS) measurements. First-principles calculations elucidate the effects of exohedral doping on the M@S and S@M systems, where a metallic (M) tube is either inside or outside a
semiconducting (S) one. The results demonstrate that metallic nanotubes
are extremely sensitive to doping even when they are inner tubes, in
sharp contrast to semiconducting nanotubes, which are not affected by
doping when the outer shell is a metallic nanotube (screening effects).
The theoretical predictions are in agreement with RRS data on Br-2- and
H2SO4-doped DWNTs. These results pave the way to novel nanoscale
electronics via exohedral doping.
