The Bi{sub 2}Te{sub 2.85}Se{sub 0.15} solid solution is an optimal material for n-arms of thermoelectric coolers operating in the range of 250-400 K. The use of Bi{sub 2}Te{sub 2.85}Se{sub 0.15} single crystals in thermoelectric coolers substantially improves their power parameters and raises the maximum degree of cooling {Delta}T{sub max}, and extends the range of their application in cooling microdevices of various types. The objective of this work was to investigate the effect of growth conditions and the purity of starting materials on the axial and radial homogeneity of Bi{sub 2}Te{sub 2.85}Se{sub 0.15} single crystals.
