Electrochemical Tunnel Etching of Aluminum

Journal of The Electrochemical Society, 1984
Anodic dissolution of aluminum in hot chloride solutions produces a high density of fine etch tunnels that extend along [100] directions. Tunnels evolve from cubic etch pits when all but one of the pit wall surfaces become passivated; dissolution then occurs at the one active face at a rate that may initially be as high as 20 A/cm2. Tunnels have square

Tailoring the morphology and electrochemical properties of Co-ZIF-L derived CoNi layered double hydroxides via Ni2+ etching towards high-performance supercapacitors.

Journal of Colloid and Interface Science, 2022
The metal ion etching induced transformation of zeolitic imidazolate frameworks (ZIFs) to layered double hydroxides (LDHs) is closely related to the etching conditions.

Machine for electrochemical etch stop

SPIE Proceedings, 2001
The configurations of electrochemical silicon etch-stop are discussed in this paper. An electrochemical etching machine with software and hardware, which can control the etching process of silicon very well, is designed and fabricated bas don the theory of electrochemical etching.

Note: Electrochemical etching of sharp iridium tips

Review of Scientific Instruments, 2011
We describe an etching procedure for the production of sharp iridium tips with apex radii of 15–70 nm, as determined by scanning electron microscopy, field ion microscopy, and field emission measurements. A coarse electrochemical etch followed by zone electropolishing is performed in a relatively harmless calcium chloride solution with high success ...

Ultrasonic characterization of electrochemically etched porous silicon

Japanese Journal of Applied Physics, 2014
This paper presents a non-destructive characterization of porous silicon wafer using ultrasound based on the strong relationship between porosity and acoustical parameters. Transmission coefficients are measured using broadband water immersion method and compared to theoretical ones using a genetic algorithm optimization.

Intermediate Structures of Pt-Ni Nanoparticles during Selective Chemical and Electrochemical Etching.

Journal of Physical Chemistry Letters, 2019
Both chemical and electrochemical etching are effective methods for tailoring the surface composition of Pt-based catalytic bimetallic nanoparticles (NPs).

ELECTROCHEMICAL ETCHING REGISTRATION AND TRACK FORMATION TIME

Nuclear Tracks, 1981
ABSTRACT The registration efficiency of electrochemically etched nuclear track detectors is highly dependent on the track-formation time. Surface defects leading to background spots start forming trees since the beginning of the etching and they may propagate extensively if the track formation is not fast enough.

Long Germanium Nanowires Prepared by Electrochemical Etching

Nano Letters, 2006
Germanium (Ge) nanowires have been produced by electrochemical etching of single-crystalline n-type Ge [100] in a HCl-containing aqueous electrolyte. Macropores could be etched at various etching currents after an optimized procedure for homogeneous pore nucleation was used.

Structural and luminescence studies of stain-etched and electrochemically etched germanium

Thin Solid Films, 1995
Luminescence from stain-etched and electrochemically etched germanium samples was observed in the blue part of the visible spectrum. Although it is weaker than the luminescence of porous silicon, its origin is of scientific interest as a parallel to the luminescence of porous silicon. Stain-etched germanium was studied in more detail.

A study on the microstructural changes and mechanical behaviors of carbon fibers induced by optimized electrochemical etching

Composites Part B: Engineering, 2019
In this study, surface defects and the surface layer of carbon fibers (CFs) were etched using a well-known electrochemical oxidation method to enhance the CFs’ mechanical properties.
