Abstract

The anisotropic and inhomogeneous dispersion ofevaporated thin films are considered in this paper. We present possible models of both based on the basic dispersion equation, and discuss methods to measure dispersion of both anisotropic and inhomogeneous indices, n(, 0) and n(X, t), respectively . These methods are applied to a series of ZnS thin films deposited with a range of incident angles [0] and thicknesses [1]. The coefficients in the proposed dispersion models have been computed according to the experimental results for 0 nm < t < 150 nm for n(A, t) and over 0° < 0 < 500 for n(0). We conclude with an analysis and discussion of both indices.
