A 2D penta-graphene sheet was cut along typical crystallographic in order to construct various penta-graphene nanoribbons (PGNRs). Their electronic and thermal transport properties are investigated through using the density functional theory in combination with the nonequilibrium Green's function method. Under various bias voltages, the electronic transport in the systems have been studied. The I−V characteristics have been extracted. DOS and T(E,Vbias) have been investigated for four Penta-Graphene nanoribbons (ZZ, ZA, AA and SS – Z: Zigzag, A: Armchair, S: Sawtooth). The calculated results show that the electronic transport properties of PGNRs are significantly different from the Graphene Nanoribbons (GNR). More interestingly, the study on the thermoelectric transport shows that the dimensionless figure of merit, ZT of the AA-PGNR is as high as 1.2 at room temperature. These results might be interesting in terms of both the fundamental science and the potential applications.
