Self-assembled silane monolayers: A step-by-step high speed recipe for high-quality, low energy surfaces

Silanization bases on the adsorption, selfassembly and covalent binding of silane molecules onto surfaces, resulting in a densely packed self-assembled monolayer (SAM). Following standard recipes, however, the quality of the monolayer is often variable and therefore unsatisfactory. The process of self-assembly is highly affected by the chemicals involved in the wet-chemical process, by the ambient parameters during preparation such as humidity or temperature and by possibly present contaminants (or impurities). Here, we present a reliable, efficient, and wet-chemical recipe for the preparation of ultra-smooth, highly ordered alkylterminated silane SAMs on Si wafers.
