The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...

In this study, we first compare the bandgap determination methods in SiON thin films using two established techniques: Ellipsometry and Energy Loss Spectrum from X-ray Photoelectron Spectroscopy. ellipsometry case, modelled optical properties a single Tauc-Lorentz oscillator model, range 1.5 to 6 eV, while for XPS used threshold energy of O1s N1s main core levels determine bandgap. We observed ...

Light-matter interplay is widely used for analyzing the topology of surfaces on small scales use in areas such as nanotechnology, nanoelectronics, photonics, and advanced materials. Conventional optical microscope imaging methods are limited resolution to a value comparable wavelength, so-called Abbe limit, cannot be measure nano-sized structures. Scatterometry an method that can structures sma...
