Qısa məlumat

Electrical and thermal properties of single crystalline and extruded samples of a p-type Bi0.5Sb1.5Te3 solid solution with various grain sizes are studied in a wide temperature range of 80-300 K. It is revealed that the grain sizes significantly affect the values of the thermal-e. m. f. (alpha), electrical conductivity (sigma), and thermal conductivity (chi) coefficients of the samples under study.
