Qısa məlumat

The electrical conductivity ( σ ), Zeebeck ( α ), Hall (Rh) and thermal conductivity ( x ) coefficients of the extruded sample of Bi2Te2.7Se0.3 with different grain sizes are investigated in the temperature range of ~77-300 K after extrusion and the same samples passed annealing. It is established that when extruding samples of solid solution axial texture in the direction of the extrusion axis arises in them due to plastic deformation. There is a correlation between the degree of texture and the thermoelectric properties. Bi Te Se 2 2.7 0.3. © 2021, International Organization on 'Technical and Physical Problems of Engineering'.
