Growth of Bi–Sb alloy thin films and their characterization by TEM, PIXE and RBS

Controllable Synthesis of One-Dimensional Chinelike Superstructures of Homogeneous Bi100–xSbx Alloys via a Template-Free Electrodeposition

“…However, for each of the mixed electrolytes (solns 2–5), there was only one reduction wave, indicating that Bi and Sb were coreduced as a solid solution. The observation of a single oxidation peak corresponding to the dissolution of the solid solution confirmed this deduction. – …”

“…The prepared products were homogeneous, composition-controllable, one-dimensional, and superstructured. It is believed that all these characters can greatly improve the thermoelectric property. ,– The method used is simple, fast, and template-free. The composition and the morphology of the products can be controlled by adjusting the composition of the electrolyte and the deposition potential.…”

“…8 The electrical structure and the transport properties of the Bi 100-x Sb x alloy depend strongly on its concentration, and the alloy with x ) 4-22 is considered to be the best n-type materials for thermoelectric cooling at temperature ∼100 K. 9 Some techniques have been used to fabricate Bi-Sb alloys. [5][6][7][8][10][11][12][13] Herein, we focus on a template-free electrodeposition for the fabrication of 1D superstructures of Bi 100-x Sb x alloys. The prepared products were homogeneous, composition-controllable, one-dimensional, and superstructured.…”

Electronic properties of nano-structured bismuth-antimony materials

“…range below 100 K. In the early 1990s, Hicks and Dresselhaus pointed out that nano-structured materials may have enhanced thermoelectric gure of merit compared to their bulk counterparts. 1,2 Since then, different types of nano-structured Bi 1Àx Sb x materials, have notably drawn the attention of researchers, including nanowires, [3][4][5][6][7] thin lms, [8][9][10][11][12][13] and nano-particles. [14][15][16][17] By making these materials in low-dimensional forms, more parameters are introduced to increase the exibility and controllability of their electronic band structures and therefore, their electronic properties.…”

Change in solidification behavior of Bi–Sb10 alloy after liquid structural transition

“…Structure, composition and morphology play important roles in thermoelectric research. The properties like electrical, mechanical or chemical are strongly affected by microstructure, grain size, defects and composition [29].…”
