From: Ultra-low thermal conductivities in large-area Si-Ge nanomeshes for thermoelectric applications
(a) Thermal conductivity (κ, red triangles) and electrical conductivity (σ, black spheres) and (b) Seebeck coefficient (S, black squares) and figure of merit (zT, blue spheres) plotted versus the pore diameter of the nano-mesh. The transport properties results obtained for a Si0.8Ge0.2 continuous thin film on SrTiO3 substrate grown under the same conditions are also plotted (the bullets/shapes inside the dotted rectangle on the left of each graph).
