We report a sharp band observed at 867 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$ in polarized Raman scattering from the edge plane of highly oriented pyrolytic graphite (HOPG). Polarization measurements indicates that this band is a vibrational mode with out-of-plane'' atomic displacement which is absolutely unexpected from the factor-group analysis. This band can be assigned to the $k=0$ zone-center mode originating from the Raman-inactive ${B}_{2g}$ mode which becomes Raman active by… CONTINUE READING
