The operational navigation system for the SPM simulator

SPM: Scanning Probe Microscope

This home page aims to provide information about how to use the SPM simulator and how to apply it to practical problems for beginners, experienced users, and other wide audience.
As you go ahead page by page, we show you some questions.
Answering these questions, you will find a suitable solver for a simulation that you want to perform.
If you advance more pages further, we will show you optional modes of the solver for various numerical simulations and how to use them.
Moreover, an input screen for numerical parameters appears.
You can input physical parameters for your own simulation through the screen.

Please select one of the following two courses.

A course for beginners at the SPM simulator
From a viewpoint of types of sample materials, you can clarify calculation conditions for your simulation.

A course for experienced users at the SPM simulator
This course is suitable for users who have already purchased the SPM simulators and gained some degrees of how to use it.
Choosing the solver, you can clarify calculation conditions for your simulation.

If you want to try simulations as soon as possible, please consult a download page for project files for various examples.

This home page is designed for the following purposes:
We hope that both beginners and experienced users can use the SPM simulator with ease by referring this home page.
As you go ahead page by page with choosing preferable items from options displayed on the screens and replying questions shown on the web pages, we offer you suitable documents and suggestions for solving your problems.
They help you to perform simulations with the SPM simulator.
Moreover, as you go ahead more pages, you can find input screens.
Through them, you can edit configuration files for simulations that you want to perform.

In this home page, we offer you the following documents and other materials:

A tutorial, a manual, a guidebook in which theoretical backgrounds of the SPM simulator are explained

Movie files that explain how to use the SPM simulator
An example: Setting parameters for the STM simulation of a surface of Si(001)-3x1:H and how to start a calculation

Examples of various simulations: numerical simulation results, their configuration files, and structural data of tips and samples
An example: The STM image of a surface of Si(001)-3x1:H

Editing a template configuration file for the simulation, you can generate a configuration file for your own simulation with ease.
An example: An input screen for editing the project file. Parameters for the simulation of the STM image of an Si(001)-3x1:H surface are input.

If you have any questions, you can consult us, simulation center of Advanced Algorithm & Systems Co., Ltd., by e-mail.
In each page of the operational navigation system for the SPM simulator, we put an icon for sending us an e-mail.
Please click the icon and send us e-mails.
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.

In some web pages, we prepare forms for questions.
Using these forms, you can ask us, simulation center of Advanced Algorithm & Systems Co., Ltd., for consultation of simulations with ease.
At your request, we can carry out simulations for you using our high-performance computers.

Please enjoy the world of the SPM simulator!
