Comparison of the adjusted VDOS of low-hydrogen-content glassy carbon in this work with an ab initio LDA/GGA (local-density approximation/generalized gradient approximation) model for graphite (Wirtz & Rubio, 2004), an ab initio dispersion-corrected density functional theory (DFT-D) calculation model for graphite (Khalil, 2016) and a 72-atom ab initio model of GC (Bhattarai & Drabold, 2017). The mode symbol labels for graphite are adapted from Wirtz & Rubio. Their unlabeled peak near 200 meV occurs at the top of the LO band. |
