Raman spectroscopy has historically been used to probe
structural and electronic characteristics of graphite materials,
providing useful information on the defects (D-band), in-plane
vibration of sp2 carbon atoms (G-band), as well as the stacking
orders (2D-band).5 The G-band of graphite materials is a doubly
degenerate (TO and LO) phonon mode (E2g symmetry) at the
Brillouin zone center,6 whereas the D-band is due to phonon
branches around the K point and requires a defect for its
activation.5 The evolution of the 2D-band for different graphene
sheets has been used for determining graphene thickness as well
as for probing electronic structures through the double resonance
process.7,8 The symmetric and sharp 2D-band (～30 cm-1) can
