Fabrication of porous silicon-based silicon-on-insulator photonic crystal by electrochemical etching method
We present a fast, novel method for building porous silicon-based silicon-on-insulator photonic crystals in which a periodic modulation of the refractive index is built by alternating different electrochemical etching currents. The morphology and reflectance spectra of the photonic crystals, prepared by the proposed method, are investigated. The scanning electron micrograph and atomic force mic...
متن کاملFabrication of Arbitrarily Shaped Microelectrodes by Electrochemical Etching
Some conventional machining methods have been developed to machine microelectrodes. However, these methods still require too much time and too many resources. This paper uses electrochemical etching as an alternative method for the simple and cheap fabrication of microelectrodes. Electrochemical etching is usually considered an appropriate method of producing sharp probes. However, it is possib...
متن کاملFabrication of uniform 4H-SiC mesopores by pulsed electrochemical etching
In this letter, the uniform 4H silicon carbide (SiC) mesopores was fabricated by pulsed electrochemical etching method. The length of the mesopores is about 19 μm with a diameter of about 19 nm. The introduction of pause time (T off) is crucial to form the uniform 4H-SiC mesopores. The pore diameter will not change if etching goes with T off. The hole concentration decreasing at the pore tips d...
متن کاملDynamic Simulation of Electrochemical Etching of Silicon
In the presented work the dynamic simulation of a silicon anodization process is performed. Two mechanisms of etch form development (diffusion in electrolyte, current flow) are considered and simulated. Influence of electrolyte conductivity and radius of the opening in the masking layer is discussed.
متن کاملSynthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method
Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...
