Abstract: Upon filling, caged compounds like skutterudites can have their lattice thermal conductivity reduced by 4∼5 times compared with unfilled structures [1]. Recently, it was found that the thermal conductivity in Bi2Te3/Sb2Te3 superlattice structure is also greatly reduced, even comparing with its corresponding alloy, in the cross-plane direction [2]. A fundamental understanding of thermal conductivity reduction in these structures is important due to their enhanced thermoelectric figure of merit. For filled skutt… Show more
