It may be argued that silicon, carbon, hydrogen, oxygen, and iron are among the most
important elements on our planet, because of their involvement in geological, biol-ical, and …

For the formation of PS dielectric filters a detailed calibration of the etch rates and refractive
indices is required. The effective dielectric function of PS was determined for different …

Multilayer films with continuously varying indices for each layer have attracted great deal of
attention due to their superior optical, mechanical, and thermal properties. However …

X-ray reflectivity (XRR) was used to investigate the p−-and p+-type porous silicon (PS)
layers. For p−-type samples, a linear dependence of the thickness versus the anodization …

Water vapor adsorption and liquid penetration into thermally oxidized porous silicon films
were studied by variable angle spectroscopic ellipsometry. Characterization of the surfaces …

A dynamical theory of X-ray coherent scattering of spatially restricted beams in porous
crystals has been developed. The solutions have been obtained for the amplitude …

Optical properties of porous silicon superlattices are investigated using variable angle
spectroscopic ellipsometry. Different phenomena such as in-depth inhomogeneities and …

This thesis presents novel methodologies to integrate AI-driven and physics-inspired
methodologies into photonic inverse design, setting new benchmarks for high-performance …

We investigate porous silicon Bragg reflectors in a nondestructive manner using variable
angle-of-incidence infrared spectroscopic ellipsometry. In addition to the thickness, volume …
