The quantum mechanical SPM simulator: DFTB


Simulating an STM image of a surface of Au(001)-5x1

A movie file that explains how to use the DFTB: setting configuration data and starting a calculation

A movie file that explains how to use the DFTB: showing results of the calculation

A document that explains how to use the DFTB (an Excel file)

Structural data of the sample material in the XYZ coordinate format

Structural data of the tip in the XYZ coordinate format

A project file for carrying out the simulation
[This is one of input data files for carrying out the simulation introduced in this web page with the DFTB. Its filename extension is ".pro".]

A screen for editing the project file Using this screen, you can edit the project file introduced in this web page.
To perform your own task which is slightly different from the simulation introduced in this web page, you can edit the project file and change input parameters.

If you have any questions about how to use the DFTB, 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.
