NDC600

Nano-Depth Composition Analyzer
based on Auger Electron Spectroscopy (AES) Model NDC600

Description

Model NDC600 analyzer is the single stage cylindrical mirror analyzer (CMA) comprising of an axial miniature electron gun with robust tungsten filament. The energy resolution of the analyzer is 0.5 %. The signal detector is based on cylindrical slit followed by channel electron multiplier with gain greater than 3x10-7.

The high elemental sensitivity is achieved by combination of high gain - low noise Channeltron TM operated with sophisticated external bandpass filter for Auger signal processing. The Auger's signal detection is from 0.1 nm to 5 nm depth at the substrate surface.


Features

  • High Surface Elemental Sensitivity
  • Small Beam Size
  • Suitable for Depth Profiling
  • Adjustment for Sample Positioning & Retraction
  • Compact Design

Applications

Nano-depth composition analyzer, model NDC600 is a simple and convenient surface chemical compositions analysis tool to be used for characterization of a wide range of materials such metals, alloys, oxides, nitrides, and thin films.

Processes such as depth profiling with separate ion sputtering gun model IG70 can be performed. In addition, the diffusion, intercalation and segregation processes can be monitored under the sample cooling and annealing treatments.
