Among our findings we have established the role that interfaces play in determining the thermoelectric response of GNR systems both across single junctions and in periodic superlattices. In general, increasing the number of interfaces in a single GNR system increases the peak ZT values that are thus maximized in a periodic superlattice. Moreover, we proved that the thermoelectric behavior is largely controlled by the width of the narrower component of the junction. Finally, we have demonstrated that chevron-type GNRs recently synthesized should display superior thermoelectric properties.}, number={37}, journal={Journal of Physics: Condensed Matter}, publisher={IOP Publishing}, author={Chen, Y and Jayasekera, T and Calzolari, A and Kim, K W and Buongiorno Nardelli, M}, year={2010}, month={Aug}, pages={372202} }
