Line Plot from Scientific Research

Energy bands as a function of the wavevector k and density of states of PGNR. The energy band gap (E g), valence and conduction bands, and effective mass (m CB and m VB) are shown; energies are reported relative to the intrinsic Fermi level (E F). The colour scale for PGNR represents the proportion of electron density on GNR (blue) or porphyrin (orange); occupied (unoccupied) levels are shown as solid (dotted) lines.
