As the range of 0.00 to -0.20 V was used, Selleckchem TPCA-1 the main element in the deposited materials was Te. As the voltage was smaller than -0.30 V, the driving forces of reduction for Bi and Sb increased

and the concentrations of Bi and Sb in the deposited compositions increased. Finally, the electrolyte formula of 0.015 M Bi(NO3)3-5H2O, 0.005 M SbCl3, and 0.0075 M TeCl4 in the pulse deposition process was used to deposit (Bi,Sb)2 – x Te3 + x nanowires. As the reduced voltage was -0.4 V, the t on/t off was 0.2/0.6 s, and the cycle time was 105, the (Bi,Sb)2 – x Te3 + x -based nanowires were successfully grown in AAO templates. The nanowires had the average length of 28 μm and the diameter of about 250 nm, and the atomic ratio for Bi/Sb/Te was 4.12:32.05:63.83.
