Structural Properties of graphene-BNNT heterojunctions.

Microscopic images of graphene-BNNT heterojunctions obtained by (a,b) scanning electron microscopy (SEM) and (c,d) transmission electron microscopy (TEM). (e) Raman spectra obtained from as-grown graphene-BNNTs in comparison with the spectra from the multilayered graphene (inset). The diameters of these BNNTs are typically 20–80 nm.
