Assessment of Defects and Collapsed Sites in Self-Assembled Alkanethiol Monolayer on Gold by Cyclic Voltammetry and A.C.Impedance
摘要:
Self-assembly of octadecyl mercaptan on gold was investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Results of CV experiments show that there are no structural defects exposed directly to the redox couple in solution, but EIS experiments indicate that collapsed sites exist in the monolayer. A method to estimate the degree of disorder in the Au/thiol monolayer surface is proposed by using admittance plane plot.
