UV laser-assisted fabrication of ridge waveguides in lithium niobate crystals

, 2010
We present a UV laser-assisted method for the fabrication of ridge waveguides in lithium niobate. The UV laser irradiation step provides the refractive index change required for the vertical light confinement in the waveguide and also defines the ...

Basic Studies on the Wet Chemical Etching of Metal Surface [PDF]

, 2002
Wet chemical etching is used for making microscopical products like lead frames, printed wiring boards, shadow masks and so on. We have investigated the temporal behavior of etching processes of stainless steel (SUS304TA) pre-treated with ultraviolet ...

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

Degradable, Skin‐Conformal Nanocomposite‐Based Bioelectronic Patches for High‐Fidelity Electrophysiology and Gesture‐Controlled Robotics

Advanced Functional Materials, EarlyView.
A degradable, skin‐conformal bioelectronic patch combines a starch‐dominated nanocomposite conductor with a gelatin substrate to enable sensitive strain sensing, high‐fidelity electrocardiography, electromyography, electrooculography, and machine‐learning‐assisted gesture control.

Measurement of threading dislocation densities in GaN by wet chemical etching

, 2006
We demonstrate a technique based on wet chemical etching that enables quick and accurate evaluation of edge- and screw/mixed-type threading dislocations (TDs) in GaN. Large and small etch pits are formed by phosphoric acid on the etched surfaces.

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Application of wet chemical etching in fabrication process of GaAs/AlGaAs quantum dot arrays

, 2000
Two types of GaAs/AlGaAs quantum dot arrays with different dot size were fabricated by dry etching and dry-wet etching. PL spectra of the arrays at low temperature show the blue shifts due to the quantization confinement effects, and the blue shift ...
