Study on Microcontamination of Silver onto p-Type Crystalline Silicon(111) from an Aqueous Solution Using Cyclic Voltammetry

The microcontamination process of silver onto p-type crystalline silicon(111) in a solution of 0.01 mol L⁻¹ AgNO₃ at room temperature was investigated by studying the anodic stripping behavior using cyclic voltammetry (CV). This paper shows that the rate of Ag deposition is rapid and that deposition is almost fully accomplished within 1 s. Calculating the surface coverage (Γ) for 1 s, 10 min, or 1 h immersion based on the CV curves demonstrated that the silver layer was only a monolayer.
