The calculated phonon thermal conductivity of the functionalized ZGNR as functions of (a) alkyl carbon atom number (n) for monofunctionalization and (b) functionalization concentration (ρ) of methyl group, compared with the pristine ZGNR. Here, the studied ZGNR measured 16 nm in length and 4 nm in width.
