Optical characterisation of RF sputter coated palladium thin films for hydrogen sensing [PDF]

open access: yes, 2011
We investigate the optical properties of Pd thin films of the thickness 20-100nm deposited on Si wafer via RF sputter coating. The Pd samples are characterised using white light interfermometry for thickness and ellipsometry for refractive index.
