DIRECT FUNCTIONALIZATION OF SILICON VIA THE SELF-ASSEMBLY OF ALCOHOLS

The reaction of fluoride-etched silicon surfaces with a range of alcoh ols yields self-assembled films which involve direct bonding to silico n in contrast with the usual oxide-based methods. Contact-angle measur ements and electrochemistry have been used to confirm the adsorption o f alcohols on fluoride-etched silicon (111) wafers. This method provid es a convenient route to the design of molecular-based structures on s ilicon.
