A new technique is developed to fabricate biomimetic antireflection coatings (ARCs). This
technique combines a bottom-up fabrication approach (glancing angle deposition, or GLAD) …

To comparative study on the growth behavior and structural properties of thin films, in this
work, we have deposited the titanium oxide (TiO2) thin films on both Si (100) and Si (111) …

Glancing angle deposition (GLAD) is a thin film deposition technique capable of fabricating
columnar architectures such as posts, helices, and chevrons with control over nanoscale film …

A series of titanium oxide films have been synthesized on silicon wafers by ion beam
enhanced deposition at different O2 pressures. X-ray Photoelectron Spectroscopy (XPS), X …

An effective medium theory is developed for periodic stacks of thin films A and B, one or both
of which may be birefringent because of an effect such as columnar microstructure. The …

Porous structured films grown with the glancing angle deposition technique have been
widely studied for thin film optical device applications. We report the use of ion assistance to …

" Why Are Optical Coatings So Awkward?" was the title of a private conference AH Macleod
gave a few years ago. Indeed, optical properties appear to be more complex and …

Microstructure and properties or thin films can be modified by ion beam irradiation during
growth. The stoichiometry, density, crystallinity, and texture of ZrO2 films deposited under ion …

Consequences of the columnar microstructure of dielectric thin films deposited by
conventional vacuum evaporation are discussed. A model associated with the columns is …

Guided wave techniques are powerful to study the properties of different optical coatings.
The latest results are presented to illustrate the interest of these techniques: the dependence …
