Description
Summary:The influence of the quantitative composition of the electrolyte and galvanostatic electrolysis conditions on the composition of thin Bi 2 Se 3 semiconductor films electrochemically deposited in the galvanostatic mode from a solution of Bi(NO 3 ) 3 ·5H 2 O and H 2 SeO 3 in ethylene glycol was studied. The results show that, with an increase in the current density and H 2 SeO 3 concentration, the bismuth content of the thin films decreases. As the electrolyte temperature, Bi(NO 3 ) 3 ·5H 2 O concentration, and electrolysis time are increased, the bismuth content of the thin films increases. The optimum electrolyte composition and electrochemical deposition conditions for obtaining thin Bi 2 Se 3 films of the composition close to stoichiometric were determined.
