Cross-section HRTEM image of a point along the layer. The thickness of the layer is . The thickness of the interfacial layer is .
Comparison of the imaginary part of the dielectric function for obtained by three different models: Cody–Lorentz model, Tauc–Lorentz model, and the Cody–Lorentz model without an interfacial layer. The Cody–Lorentz model reports a significant increase in absorption over the Tauc–Lorentz model.
Imaginary part of the dielectric function obtained with the Cody–Lorentz model. For films with silicate % range from 10% to 80%.
Thickness of the film stack modeled by the Cody–Lorentz and Tauc–Lorentz model and compared with TEM results. All thickness values reported in Angstroms.
