Description
Summary:The results of electropolishing on both p- and n-type bismuth alloys doped with antimony were reported. The current-voltage measurements were carried out to optimize current density and the surfaces of the samples were examined by scanning electron microscopy (SEM). The qualitative and quantitative analysis of ionic concentration of Selenium (Se) and Antimony (Sb) in the particular area of electropolished electrolyte of n and p-type Bi sub(2)Te sub(3) based alloys was done using polarigraphic techniques. The qualatative analysis of Tellurium indicated its diffusion current and half wave potential.
