- •
The total thermal conductivity decreases from 1.8 to 0.9 Wm–1K–1 at 300–873K.
- •
The electrical conductivity decreased from 850 to 163 S/cm at 300–873K.
- •
The Seebeck coefficients were enhanced through heavily Iodine doping.
- •
The ZT ~0.06 at 873K suggests that Bi2YO4Cu2Se2 systems are potential thermoelectrical materials.
