Differential reflection spectroscopy of very thin surface films

摘要: Abstract The influence of thin adsorbed films on the reflectance properties two-phase systems is discussed. It shown that linear approximation to normalized reflectivity change ΔR R reduces complicated expressions for multiphase stratified a simple form which gives direct physical insight into these systems. Several interfacial interest are examined in detail, and results generalized include attenuated total reflection, fractional coverage, interfaces with smoothly varying optical properties.
