  • Method and apparatus of determining optical constants of amorphous semiconductors and dielectrics
    Patent number: 4905170
    Abstract: Disclosed is a method of and apparatus for determining the optical constants of materials in general and also for determining thicknesses of thin films. A complex index of refraction is derived that provides excellent fits to the measured n and k values of a large number of materials (including semiconductors, dielectrics, and metals) over a wide range of photon energies covering almost the entire range of the spectrum of electromagnetic radiation, including infrared, visible and ultraviolet.
