摘要
The effects of back-surface reflection from transparent substrates on ellipsometric measurements are discussed and it is shown that their effects can be minimized by placing the substrate on a commercially available product, Blu-tack. The ellipsometric properties of Blu-tack in the range 250-850 nm are presented and the frustration of the back-surface reflection is discussed in terms of index matching between substrate and Btu-tack.
