Hydrothermally synthesized and hot-pressed Bi2(Te,Se)3 thermoelectric alloys

Low-Temperature Thermoelectric Properties of β-Ag2Se Synthesized by Hydrothermal Reaction

“…More importantly, the method is able to produce highpurity powders, and the size and morphology of the products can be well controlled. [4][5][6][7][8] b-Ag 2 Se has been synthesized by solid-state reaction 2 or mechanical alloying. 3 Recently, several groups have reported wet chemical synthesis (including hydrothermal preparation) of the compound.…”

Surfactant-assisted solvothermal synthesis of single-crystalline ternary Bi–Sb–Te hexagonal nanoplates

“…The binary Bi 2 Te 3 nanostructure with various morphologies such as nanoparticles [10][11][12], nanosheets [13], nanowires [14,15], hollow nanospheres [16], nanotubes [17] and nanoplates [18,19] has been prepared by solvo/hydrothermal method, wet chemical reactions. Bi 2 (Te,Se) 3 nanoparticle [20], Bi 2 Te 2.7 Se 0.3 and Bi 0.5 Sb 1.5 Te 3 nanocrystals [21], Bi 2 Te 2 Se and BiSbTe 3 hexagonal nanoplatelets are also synthesized by the chemical ways [22]. In this work, the morphology of ternary (Bi,Sb) 2 Te 3 nanocrystal is tried to regulate and control by the solvothermal route.…”

Improvement of Thermoelectric Power Factor of Hydrothermally Prepared Bi0.5Sb1.5Te3 Compared with its Solvothermally Prepared Counterpart

“…The size of the Seebeck coefficient of x = 0 is smaller than that of the hydrothermally synthesized and hot-pressed sample. 8 However, the room-temperature resistivity of our x = 0 sample is slightly lower than the latter. The size of the Seebeck coefficient for x = 1.0 is twice that in the direction perpendicular to the trigonal c-axis of a BiSbTe 3 crystal.…”
