Covalent Attachment of Acetylene and Methylacetylene Functionality to Si(111)Surfaces:Scaffolds for Organic Surface Functionalization while Retaining Si-C Passivation of Si(111)Surface Sites

摘要

Covalent attachment of organics to Si has attracted much attention,due to the ability to passivate the Si surface toward chemical oxidation while retaining desirable electrical properties.Functionalization methods include alkyl-Grignard or alkyllithium reagents,hydrosilylation,electrochemical grafting,and mechano-chemical functionalization.
