Template assisted fabrication technique towards Si-inverse opals with diamond structure
نویسندگان
چکیده
A method to fabricate silicon (Si) inverse opals with diamond structure is introduced. The method is based on the arrangement of silica particles in a template consisting of Si pillars periodically distributed. The profile of the pillars is specially designed to induce the self-organized growth of the particles in a diamond lattice along the (1 1 0) direction. Afterwards, the inverse structure is achieved by infiltrating the opal with Si and subsequently removing the silica by chemical means. Different from a former approach based on robotic manipulation, this method allows the fabrication of large samples available for integration in planar photonic devices. # 2004 Elsevier B.V.

Sacrificial-Layer Atomic Layer Deposition for Fabrication of Non-Close-Packed Inverse-Opal Photonic Crystals
Photonic crystals have been studied extensively for their potential to control and manipulate light, similar to the way electrons are controlled in a semiconductor, opening the door to high-speed, low-power, all-optical devices. A common method for fabricating 3D photonic crystals is the infiltration and subsequent inversion of synthetic opal templates to create inverse opals consisting of air ...

The fabrication of high optical quality inverse opals is challenging, requiring large size, three-dimensional ordered layers of high dielectric constant ratio. In this article, alumina/TiO2-air inverse opals with a 98.2% reflectivity peak at 798 nm having an area of 2 cm2 and a thickness of 17 µm are achieved using a sacrificial self-assembled structure of large thickness, which was produced wi...

An advanced dielectric function has been designed to compute the photonic band structures of non-close-packed inverse opals fabricated using conformal infiltration and by a recently described sacrificial-layer technique. A model is proposed to correctly simulate complex dielectric structures resulting from conformal backfilled infiltrations. While large photonic band gaps PBGs and a reduced ref...

متن کاملEnzyme-based inverse opals: a facile and promising platform for fabrication of biocatalysts.
A facile and promising approach was developed to fabricate enzyme-based 3D-ordered macroporous biocatalysts (enzyme-based inverse opals) by using the colloidal crystal templating method. Horseradish peroxidase- and amylase-based inverse opals were prepared, which verified that this method is suitable for various enzymes.
