General description

Our gold-coated silicon wafers use electron-beam lithography to form amorphous layers (50Å of titanium followed by 1000Å of gold) on top of the silicon wafer.
The product is highly crystalline, with <111> orientation gold and <100> orientation silicon wafer is used. Titanium is used as an adhesion layer to bind gold to the silicon wafer.

Application

Gold coated silicon wafers may be used in soft lithography for micro and nanoscale patterning.

Displaceable Monolayers and Microdisplacement Printing: 1-Adamantanethiol Assembly and Applications

1-Adamantanethiol (1-AD), an example in this spectrum of molecules with distinct chemical and physical properties, forms self-assembled monolayers (SAMs) on Au{111} that are displaceable when exposed to other thiolated molecules from solution, vapor, or contact due to weak intermolecular interactions in 1-AD SAMs.

Synthesis of Melting Gels Using Mono-Substituted and Di-Substituted Alkoxysiloxanes

Hybrid organic-inorganic sol-gel materials containing silica were first called “ORMOSILs” in 1984.
