The magnetic field was aligned along the thickness t of a sample and the current flows along its length L through the copper leads soldered to both end surfaces of cross section (W×t), where W, t and L are parallel to the binary, bisector and trigonal axes of the single-crystal, respectively. The thermoelement was not in contact with a heat sink. The cooling temperature of Bi0.85Sb0.15 at 290K was increased with an increase of B and was almost symmetric for the reverse of the field direction, while at 113K it exhibited a maximum at B=±0.25T and a strong asymmetry for the field direction. The largest maximum cooling temperature ΔT max of Bi0.85Sb0.15 was achieved when a thermoelement has optimum dimensions so that heat energy is hardly generated at the cold side. When the single-crystal Bi0.85Sb0.15 alloy has optimum dimensions of L=15mm, W=4mm and t=2mm, the ΔT max at 290K increased from 4.2K in B=0T to 9.6K in B=+2.17T, so that it exceeded ΔT max values of 5.7K obtained for a typical Bi2Te3 and 8.5K measured previously for Bi single-crystal in B=+2.17T.
