SPM simulator: high polymers and soft matters (01)

In this page, we choose environment where the SPM experiment is performed.
Please select environment between air environment and liquid environment.
If you carry out SPM experiments in vacuum environment, please choose air environment as an approximation.

In this page, we suppose that the sample material is a high polymer or a soft matter.
However, we can apply a method discussed here to organic compounds, metals, semiconductors, and non-organic compounds, as well.

Do you perform the SPM experiment in air environment or in liquid environment?

Air environment

We simulate the AFM experiments in air environment.
Regarding tips and samples as continuous masses, we simulate deformation of tips and samples due to the van der Waals forces.
Neglecting the deformation of tips and samples, we can simulate AFM images very quickly.
From an experimental AFM image, we can estimate a shape of the tip.
Considering viscoelastic contact mechanics, we can simulate adhesion between the tip and the sample material that has viscosity and surface tension.

Liquid environment

We simulate the AFM experiments in liquid environment.
We can calculate the AFM force curve, that is to say a force-distance plot generated by dynamics of the tip.
We can estimate a resonant frequency of the cantilever of the AFM.
Considering viscoelastic contact mechanics, we can simulate adhesion between the tip and the sample material that has viscosity and surface tension.

If you cannot find a simulation that you want to perform from the above list, please contact us by e-mail.
When you send an e-mail to us, a string of characters is put into a subject of the e-mail automatically.
This string tells us at which stage of the simulation you have a trouble.
