Applicazioni

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.
Titanium adhesion layer used to bind the gold to an aluminasilicate glass microscope slide. Titanium thickness ~20 angstroms.

Caratteristiche e vantaggi

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