Covalently linked organic monolayers on silicon surfaces provide a prime example of hybrid electronic materials. Such systems are required on the one hand to passivate the Si surface, and on the other hand provide an optimal electrical link between the bulk of the Si semiconductor and the liquid with which it interacts.
To obtain an optimal passivation a highly dense monolayer is required, and we present novel agents and methods that yield a denser formation of the monolayers. At the same time monolayer formation can be made faster, which reduces the chance for competing silicon oxide formation. Finally, this combination of properties is desired for really thin monolayers, which drives research to allow attachment of small molecules. The paper will present a combination of such newly developed methods, properties of the resulting monolayers and an approach for further systematic improvements.
