摘要：

Results from electrochemical impedance spectroscopy measurements of gold electrodes, which were modified by immersion in solutions of alkanethiols and other sulfur-containing derivatives, are reported. Three cases were investigated: a capacitive system, a completely covered and a partially covered electrode. A proposed model considers both through-film and at-defect electron transfer paths, and is compared with experimental results.
