Application

Titanium adhesion layer used to bind the gold to an aluminasilicate glass microscope slide. Titanium thickness ~20 angstroms.
Gold coated microscope slide can be used as a substrate material that facilitates the formation of highly active surfaces for surface enhanced Raman scattering (SERS) measurements.

Features and Benefits

The gold surface shows a tendency towards <111> orientation.
