Fig. 2From: Thermoelectric composite with enhanced figure of merit via interfacial dopingTransport properties of a composite made of Pb-coated glass beads in a (Bi0.25Sb0.75)2Te3 host matrix. The thermopower, resistivity, power factor (α2σ), and Hall carrier concentration are shown as functions of temperature for the various volumetric filling fractions indicatedBack to article page
