Description
Silicon wafers coated with high purity gold (99.999%) exhibit high electrical conductivity and high reflectivity. Our gold coated wafers feature a thin titanium adhesion layer to ensure proper adhesion of the gold layer to the silicon substrate.
This product can be used as a substrate for analytical characterization of thin films, nanoparticles, proteins and self-assembled monolayers via electrochemistry, IR spectroscopy, Raman spectroscopy, X-ray spectroscopy, or ellipsometry. Gold-coated wafers are also ideal substrates for fabrication of complex electrochemical devices.
Gold-coated silicon wafers, and gold-coated silicon chips, are used extensively as substrates for analytical characterization of materials. For example, materials deposited onto gold-coated wafers can be analized via ellipsometry, Raman spectroscopy or infrared (IR) spectroscopy due to the high-reflectivity and favorable optical properties of gold. In addition, gold-coated silicon wafers are excellent substrates for fabricating electrodes, electrochemical sensors, self-assembled monolayers, photonic devices, and other advanced technologies.
