Influence of Eu-doping on transport properties of synthesized zintl phase compounds EuxYb1−xZn2Sb2 under microwave-assisted solid-state
In this work, synthesis and characterization of EuxYb1−xZn2Sb2 (0 ≤ × ≤ 1.0) systems under microwave irradiation method. Herein, microwave technique offers ecological merit in the synthesis of thermoelectric materials such as short duration (25 min). The synthesized samples were analyzed by their XRD, SEM, EDX, Seebeck coefficient, electrical conductivity, and Hall voltage measurements. The microwave synthesis of compounds by doping Eu into YbZn2Sb2 and their properties are extensively discussed. It was found that the microwave irradiation acts to accelerate the reactions induced by fast heat surrounding susceptor of primary components and give large quaternary ingots. The XRD data revealed that the synthesized compounds crystallized in a hexagonal structure where ZnSb precipitated as a secondary phase in almost all the synthesized adopted compounds. Furthermore, a maximum PF of 26.27 μW/cmK2 at 518 K was acquired for Eu0.6Yb0.4Zn2Sb2 sample with carrier concentration of 5.11 \(\times \) 1021 cm−3 at 300 K.
