Optical and nanostructural insights of oblique angle deposited layers applied for photonic coatings [PDF]
Applied Surface Science, 2020 Oblique angle deposition (OAD) is a nanostructuration method widely used to tune the optical properties of thin films. The introduction of porosity controlled by the deposition angle is used to develop the architecture of each layer and stack that enable modifying and optimizing the optical properties of the constituent layers for optimal design ...
