How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Controlled Air Gap Formation between W and TiO2 Films via Sub‐Surface TiO2 Atomic Layer Etching

open access: yesAdvanced Materials Technologies, EarlyView.
Delivering SiH4 and WF6 to a lined array of TiO2 films produces a thin film of tungsten while simultaneously, the underlying TiO2 is removed. When the W‐coated TiO2 structure is exposed to further etching cycles after deposition, TiO2 etching continues vertically and laterally, creating a self‐supported W structure and a vacant air gap.

Pattern formation without heating in an evaporative convection experiment [PDF]

open access: yes, 2003
We present an evaporation experiment in a single fluid layer. When latent heat associated to the evaporation is large enough, the heat flow through the free surface of the layer generates temperature gradients that can destabilize the conductive ...

Direct Growth of Rectangular 2D Layered Metal‐Halide Perovskite Microcrystal Photonic Cavities on Functional Substrates

open access: yesAdvanced Optical Materials, EarlyView.
A simple and scalable method to fabricate 2D layered metal halide microcrystals with rectangular shape, extremely flat surfaces, and submicron thickness is presented. The growth occurs in evaporating droplets on planar substrates, which enables the fabrication of the microcrystals directly on functional surfaces. The microcrystals demonstrate excellent

Pressure‐Assisted Ceramic Processing of Metal Halide Perovskites

open access: yesAdvanced Photonics Research, EarlyView.
This review critically assesses low‐temperature, pressure‐assisted ceramic processing as a pivotal technique to fabricate dense, polycrystalline wafers with precisely controlled macroscopic dimensions as well as microstructural properties. The aim is to bridge understanding between expert ceramists and halide perovskite specialists, highlighting the ...
