(a) Band structure of a zGNR/zBNNR superlattice consisting of 2 dimer lines of zGNR and 6 dimer lines of zBNNR [176]. (b) Seebeck coefficient as a function of bandgaps for the zGNR/zBNNR superlattices [176]. Squares, circles, and triangles are for 150 K, 300 K, and 450 K, respectively. (c) Cross-plane thermal conductivity of superlattice, random multilayer, rough superlattice, and random alloy for a Lennard-Jones type conceptual crystal [33]. (d) Thermal conductivity of conceptual Lennard-Jones superlattices and random multilayers as a function of average layer thickness [34]. Panels (a)–(c) are reproduced with permission [33, 176].
