    • Substrates with SWNTs were typically characterized by scanning electron microscopy after the AFM and PL experiments to avoid any possible damage of nanotubes by the electron beam. SEM images of nanotubes could then be readily correlated with the AFM and PL data due to markers on the substrates.

    • The increase in emission from the stretched segment of SWNT 1 between positions -30 and -105 μm in Fig. 5 is due to a Raman overtone, which overlaps with the strain-shifted E11 - E22 emission-excitation PL peak.

    • The conventional (n,m) notation with positive indices n, m, and n≥m corresponds to right-handed SWNTs (following the usual definition for helical structures). Their left-handed counterparts can be indexed, for instance, as (m,n) nanotubes.

    • Note that axial and torsional strains are coupled in a chiral nanotube. However, axial strain generated by pure torsion and the corresponding E11 and E22 energy shifts are expected to be relatively small (see also Ref.).
