Semiconducting Behavior of Non-Solid Electrochemical State of Carbon Steel in Electrolyte Solution

Abstract:

In this paper, the semiconducting behavior of non-solid electrochemical state of carbon steel in acid, base and salt solutions was studied by utilizing potential-capacitance and Mott-Schottky analysis. It was pointed out that the capacitance variation of space charge layer of non-solid electrochemical state of carbon steel in different solution was different. The non-solid electrochemical state showed p-type semiconducting behavior in 5 sulfuric acid and 5 % sodium sulfate solution. However, it showed n-type semiconducting behavior in 5 % sodium hydroxide, suggesting that the space charge layer of non-solid electrochemical state of the carbon steel in different electrolytes might be asymmetric.
