Optical constants of methyl-pentaphenylsilole by spectroscopic ellipsometry
The optical properties of 1-methyl-1,2,3,4,5-pentaphenylsilole thin films grown on silicon substrate were investigated using spectroscopic ellipsometry ~SE!. Accurate refractive index n and extinction coefficient k, in the wavelength range of 250 to 800 nm, were determined. Sellmeier equations, amorphous semiconductor model, and a three-oscillator classical Lorentz model were used to fit the da...

متن کاملApplication of spectroscopic ellipsometry and Mueller ellipsometry to optical characterization.
This article provides a brief overview of both established and novel ellipsometry techniques, as well as their applications. Ellipsometry is an indirect optical technique, in that information about the physical properties of a sample is obtained through modeling analysis. Standard ellipsometry is typically used to characterize optically isotropic bulk and/or layered materials. More advanced tec...
متن کاملDetermination of AlAs optical constants by variable angle spectroscopic ellipsometry and a multisample analysis
Determination of AlAs optical constants by variable angle spectroscopic ellipsometry and a multisample analysis" (1995). Using variable angle spectroscopic ellipsometry, optical constants for AlAs (1.4-5.0 eV) are presented which are simultaneously compatible with measured data from four different samples. The below-gap index values are compatible with published prism measured values. The secon...
