(a) Temperature dependences of ZT values, (b) ZT values at 300 and 380 K as a function of Sb content x, as well as data from Ivanova,53 Yim,24 Fan.48 (c) Average ZTav values of the hot-deformed Bi2−xSbxTe3 bulk samples, (d) ZT values of the Bi0.3Sb1.7Te3 samples prepared several times to demonstrate processing repeatability, and (e) the maximum ZT value compared with some other typical work using the traditional composition Bi0.5Sb1.5Te34, 6, 8, 24 (The yellow-shadowed part indicates the overvalued ZT determined by in-plane σ and out-of-plane κ.).
