Setup descriptionPorous silicon is electrochemically produced by applying anodic voltage across the top and bottom of a silicon wafer in the electrolyte containing fluorine anions. A typical two-electrode setup for electrochemical porous silicon formation consists of: silicon wafer (working electrode - anode), platinum electrode (counter electrode -cathode), etching solution (HF based electrolyte), etch cell and power supply. A three-electrode setup is additionally equipped with...

[online] redox.me Available at: https://redox.me/blogs/good-measurement-practices/troubleshooting-electrochemical-cell [Accessed Date Accessed]. This post concerns a situation in which the electrochemical setup based on a cell does not seem to be producing the proper response. The specific guidelines for checking an electrochemical system and isolating the problem may be typically found in setup manual. The following post has a more general character and is based on electrochemistry handbooks [1]. Let’s consider the setup intended for CV measurements in a 3-electrode configuration. It consists of metal...
