In order to understand this, we present the band structures of left electrode/right electrode, i.e., 12ZGNRH (Figure ) and scattering region, viz, 12ZGNRH, 10ZGNRH, 8ZGNRH, 6ZGNRH and 4ZGNRH (Figure to that of Fano-type asymmetrical line shape, comprising of a resonant peak followed by an anti-resonance. Fano anti-resonance is observed when a localized state interacts with a continuum of extended states. To demonstrate that the Fano anti-resonance is associated with the localized states, we examined the PDOS spectrum. PDOS analysis reveals that these transmission dips are associated with strongly localised DOS peaks near Fermi level arising from the edge carbon atoms (Figure in SI). This is in contrast to the multi-path DQI anti-resonances, wherein no DOS peaks are observed in PDOS spectra corresponding to sharp dips in transmission spectra. 32 To address the origin of these dips in more details, we investigated the case of 4ZGNRH exhibiting most prominent dips in transmission spectra. As illustrated in Figure , the transmission exhibits a very small dip of the order of 10
