Carbon-Based Materials for Thermoelectrics

Figure 7

(a) Scanning tunneling microscopy image of graphene nanowiggle. (b) Atomic structure of GNW. ((c) and (d)) Phonon dispersion relations and transmission functions of aGNR and its GNW counterpart. (e) Thermal conductance as a function of temperature for aGNR and the GNW shown in panel (b). (f)–(h) Electrical conductance , Seebeck coefficient S, and TE figure-of-merit ZT as a function of chemical potential at room temperature for aGNR and GNW. In panels (e)–(h), solid lines denote GNW and dashed lines denote the corresponding aGNR. All panels are reproduced with permission [103, 104].
