The highest ZTs we achieved are ~1.3 due to the combined effects of high Seebeck coefficient and low thermal conductivity, which is comparable to 1.4 of n-type Iodine doped PbTe with no special nano inclusions20. Intuitively, Al with less valence electron than Pb, it should be acceptor when it substitutes Pb.
