Effects of composition and preferred orientation on microstructure and thermoelectric properties of p-type (BixSb(1−x))2Te3 alloys

► Effect of content of X in (BixSb(1-x))2Te3 on thermoelectric properties was studied. ► Increasing Bi content was found to improve the TE properties. ► Samples compressed with parallel (//) direction have better TE properties than perpendicular (□) direction
