| 摘 要： | Pseudoternary system (Bi_2Te_3-Sb_2Te_3-Sb_2Se_3) ceramic smeiconductor cooling materials were pre-pared in solid state reaction with conventional techniques ofsintering ceramics.The effect of doping on the properties ofthe material was studied.X-ray diffraction analysis showedthat n-p-type materials were solid solutions based on Bi_2Te_3and Sb_2Te_3 respectively.SEM photographs proved that theboth types of materials were inhomogeneous and layer struc-ture.The values of fingure of merit for n-type and p-typematerials were 3.4×10~(-3) K~(-1),respectively.The fabricatedthermoelectric modlules made of the materials provided excel-lent cooling effect.
