A blunt tip reduces STM resolution, because it can cause electron tunneling to occur across a wider spatial range than intended. One of the most commonly used methods to create such a tip is ...

The primary components are a vertical salt water bath, DC power supply, metal to etch, scrap steel approximately the same size, and a water agitator, which in this case is an air pump and diffuser ...

[Gelandagan] has some templates that will allow you to make your own electro etcher, provided you can etch your own boards and can program the PIC16F1828 microcontroller. All this info is over on ...

Specialty applications include electro-chemical milling of nickel alloy parts. Materials: Aluminum; Copper; Nickel / Nickel alloys; Stainless Steel; Steel / Steel Alloys; Titanium; Tantalum, ...

Such an in situ electrochemical etching method can be used to expose various well-defined metal surfaces in solution. The atomic structures of semiconductor surfaces of Si and GaAs were successfully ...

Etching is commonly used to create printed circuit boards, semiconductors, solar cells, micro-electro-mechanical (MEMS) devices, and a wide variety of custom components. Etchers and etching machines ...

Fundamental fabrication issues for microscale components used in MEMS/Nanotechnology. Understand and designing microfabrication processes based on photolithography and deposition/etching steps. Micro ...

The etching was achieved by combining deep ultraviolet ... Another highlight is the electro-optic Mach-Zehnder modulator (MZM), a device widely used in today's high-speed optical fiber communication.
