High zT and Its Origin in Sb‐doped GeTe Single Crystals
A record high zT of 2.2 at 740 K is reported in Ge(0.92)Sb(0.08)Te single crystals, with an optimal hole carrier concentration ≈4 × 10(20) cm(−3) that simultaneously maximizes the power factor (PF) ≈56 µW cm(−1 )K(−2) and minimizes the thermal conductivity ≈1.9 Wm(−1) K(−1). In addition to the prese...
