Abstract
We studied the incidence-angle dependence of the optical reflectivity difference in response to ultrathin films on transparent and opaque substrates. We found that the classical three-layer model reproduces the experimentally obtained angular dependence for a monolayer of xenon on Nb(110) and for a monolayer of protein molecules on functionalized glass. We explore the enhancement of the optical response near the Brewster angle (or its equivalent for opaque substrates) in thin film detection.
