A microwave plasma enhanced chemical vapor deposition (microwave PECVD) process has been investigated to deposit micro crystalline silicon films with a high growth rate from silane (SiH4). A three-layer Bruggeman-Effective-Medium-Approximation (BEMA) model was developed to describe the complex structure of the grown films. The model was confirmed by Raman and spectroscopic ellipsometry measurements...
TiO2-nanoparticles under UV-light irradiation are well known for photocatalytic activities due to generated electron/hole pairs. This is investigated for widespread applications like water splitting for fuel generation, wetting of surfaces, photovoltaics or destruction of germs and bacteria on contaminated surfaces. TiO2 nanoparticles combined with copper and palladium nanoparticles show selective...
