Abstract
A consolidated effect of anharmonicity, crystallite size and defects has been studied using temperature dependent Raman spectroscopy of reduced graphene oxide (rGO). The micro-Raman spectra obtained over a wide temperature range of 173–723 K (below and above room temperature) indicate linear shifts in the peak position of G- and D- modes, with negative temperature coefficients of −0.009 and −0.010 cm−1 K−1, respectively. The average crystallite...
