Variable angle of incidence spectroscopic ellipsometry: Application to GaAs‐AlxGa1−xAs multiple heterostructures
TL;DR: In this article, the sensitivity of spectroscopic ellipsometry data to multilayer model parameters is shown to be a strong function of the angle of incidence, and the maximum sensitivity to layer thicknesses and AlGaAs composition occurs near the wavelength-dependent principal angle.
Journal ArticleDOI
Modeling AlxGa1−xAs optical constants as functions of composition
TL;DR: In this article, three models for the dielectric function of Al(x)Ga(1-x)As were reviewed based on measured optical constants at discrete compositions, and the validity of each model near critical point energies, and otherwise, was evaluated.
Journal ArticleDOI
Spectroscopic ellipsometry studies of HF treated Si (100) surfaces
TL;DR: In this article, both ex situ and in situ spectroscopic ellipsometry (SE) measurements were employed to investigate the effect of HF cleaning on Si surfaces, showing that after a 20sec 9:1 HF dip without rinse, the Si (100) surface was passivated by the hydrogen termination and remained chemically stable.
