【Abstract】 The high figure of merit p-type and n-type pseudo-ternary Bi₂Te₃-Sb₂Te₃-Sb₂Se₃ Semiconductor cooling materials, which give the highest figure of merit of 3.2×10^-3/K at near room temperature, have been developed. The distinguishing feature of crystalline structure and the effect of growth conditions on the thermoelectric properties of matrial also discussed.更多还原
