Metal island film based structures for sensing using spectrophotometry and ellipsometry

Metal island films (MIF) are good candidates for sensors due to environment refractive index sensitive localized surface plasmon resonance. The strong near field enhancement in the vicinity of the island surface can be even higher if metal layer (ML) is placed close to MIF. Structures containing MIF with and without ML are prepared and sensitivities of spectrophotometric and ellipsometric features of measurements compared. It is shown that simple MIF is preferable for ellipsometric and including ML for spectrophotometric sensing
