Standard Sample for Height Calibration of AFM Instruments with the Order of Sub-Nanometer

It is well known that the step structure on silicon surfaces can be controlled by a heating process in an ultrahigh vacuum. The height of the Si(111) monoatomic step is 0.31 nm and is determined crystallographically. Anyone can use this standard sample to calibrate the height scale of an AFM instrument or estimate the instrument's performance.

A 10mm × 10mm sample can be applied to any AFM instrument. The sample is carefully packaged for delivery to prevent it from coming into contact with anything. With appropriate precautions to guard against humidity and floating particles in the air, the surface structure is good for more than 6 months.

Uses:

  • Height scale calibration
  • Estimation of instrument's performance

Standard Sample for In-depth Profiling

This is a standard test sample with multilayer films for in-depth profiling of SIMS, AES, XPS and XRF. Suitable for evaluation of resolution, distance measurement and sensitivity.

Using this standard sample, you can test:

  • in-depth resolution
  • in-depth distance
  • sensitivity

 

We can offer standard test samples of your choice in terms of material, film thickness, as well as the numbers of layers.
