TL;DR: In this article, the authors used photocurrent measurements and time-resolved laser coulostatic monitoring to elucidate the mechanism of charge injection on the modified surfaces of tin oxide and titanium dioxide semiconductor electrodes.
Abstract: Tin oxide and titanium dioxide semiconductor electrodes have been covalently modified by the attachment of functionalized olefins and arenes through surface silanation or via a cyanuric chloride linkage. The excited state and electrochemical properties of the molecules so attached are significantly affected by the semiconductor. Photocurrent measurements and time-resolved laser coulostatic monitoring have been employed to elucidate the mechanism of charge injection on these modified surfaces.
