| Abstract: | Electrochemical studies of thiol-capped semiconductor nanocrystals in an aqueous solution have demonstrated several distinct oxidation and reduction peaks in the voltammograms, with the peak positions being nanocrystal size dependent. It has been demonstrated that the method is very sensitive to the nanocrystal surface state, providing complementary information for better understanding of special optical properties of semiconductor nanocrystals. | |
