Fig. 2

a Kataura plot relating the energy of the band gaps in a carbon nanotube and its diameter. Here, red circles denote semiconducting CNTs and black circles denote metallic CNTs. Adapted from [32]. b Schematic showing the density of states and VHS peaks (indicated by a sharp maxima) of a semiconducting CNT. Arrows indicate the mechanism of light absorption and emission. Adapted from [36]
