Progress in understanding electron-transfer reactions at semiconductor/liquid interfaces

Article Abstract:

Research was conducted to examine the theoretical treatments and experimental data focused on the rates of interfacial electron-transfer processes at semiconductor/liquid contacts. The practical interest in the systems is due to the fact that they are a critical factor in understanding the behavior of photoelectrochemical cells as energy conversion devices. Their theoretical importance lies in the fact that the reaction of a delocalized charge carrier with a localized redox acceptor is a relatively undeveloped part of the electron-transfer theory.

Electrochemical properties of (111)-oriented n-Si surfaces derivatized with covalently-attached alkyl chains

Article Abstract:

Research was conducted to examine the electrochemical characteristics of alkyl-terminated, (111)-oriented, n-type Si surfaces, prepared using a two-step halogenation/alkylation method. The analysis was carried out in contact with CH3OH-1,1'-dimethylferrocene(super +/0) (Me2Fc(super+/0)) solutions. Results suggest that the electrochemical properties of the alkyl-terminated surfaces were very similar to those of the H-terminated Si surface.
