文摘
- •
Efficient thermoelectric materials are fabricated at low cost and shorter time.
- •
Bi2Te3−xSex alloys are produced by combining casting and high energy ball milling.
- •
Amount of x neither influences powder morphology nor bulk microstructure.
- •
Increase in x decreases power factor, thermal conductivity and figure of merit ZT.
- •
Bi2Te2.85Se0.15 alloy exhibits ZT higher than state of art n-type materials at 323 K.
