“…The
calculated nonresonance Raman spectra of
(0,6) @(0,n)-DWBNNTs (with cell lengths of one unit and
n=12-18) indicated that the radial breathing modes
(RBMs) of inner (0,6) and outer (0,n) tubes are not only
diameter dependent, but also exhibit a strong blue-shift
for the ΔR below ~0.35 nm and rapidly approach zero
with increasing ΔR reference to the position of the RBM in
the spectrum of the corresponding single
wall boron
nitride nanotubes, (0,n)-SWBNNTs. …”
