SPM simulator: metals, semiconductors, and non-organic compounds (011)

In this page, we recommend you DFTB as solvers that simulate AFM images of metals, semiconductors, and non-organic compounds under angstrom scale according to the quantum theory.

We recommend you the following solver:

DFTB: the quantum mechanical SPM simulator

The DFTB solver simulates STM, STS, AFM, and KPFM images of metals, semiconductors, and non-organic compounds.

Advantages of the DFTB are as follows:

The DFTB performs simulations according to the quantum theory.

The DFTB carries out calculations with the density functional based tight binding method.

You can obtain simulation results more rapidly compared with the first-principles calculation.

The DFTB can simulate AFM images of non-organic compounds put on surfaces of crystals of non-organic compounds and plates of metals.
