QSTEM SOFTWARE DOWNLOAD

It now does not crash anymore of you run simulations in box-mode and TDS turned on. This is important for bigger models. This GUI-based tool lets you build super structures containing arbitrarily many crystalline grains. However, one can prepare several simulations, save the configurations files and then run them all in parallel or even better: Added virtualGoniometer to the qstem suite. Increased the speed of model building with qmb by more than an order of magnitude.

Please do not use previous versions qste, qstem if you are working with alloys more than 1 atom per site or vacancies partial occupancies. Please make sure to update your source code if you have a version prior to March since it now includes some important bug-fixes.

These problems have been fixed now. STEM simulations are inherently slow. It also gives you the rotation angles for arbitrary zone axes.

For TEM images you should turn off TDS when simulating electron exit face wabe functions and use the ImageSim tool to compute images, focal series, or thickness-defocus maps see this tutorial.

In qmb the selection of atomic columns for moving or deleting has become more comfortable.

If you already have an image you can build the model to match the atomic column positions of the image. Much of how the STEM simulation works, and the particular strengths of the simulation software provided on this website is described in my PhD thesis.

The energy spread was not correctly considered inSTEM simulations. Includes option for computing CBED patterns and save the wave function for intermediate specimen thicknesses. Showimage can now compute quantitative STEM images qstdm absolute counts based on source brightness, convergence angle, dwell time and effective source size. The 3D view in qstem now includes different colors for different softwre. Fixed a bug in the GUI that occurred when loading non-orthogonal unit cells Improved 3D display in qstem: Personal tools Edit page.

Fixed a bug in stem3. If you are looking for presentations or tutorials about qstem, you may directly to this documentation pageor browse the qstem FAQ list.

Fixed bug in imageSim, which would display images of unequal edge length improperly. A Linux version of stem3 can be compiled from that, and a parallel version of softwqre will soon be available as well.

QSTEM v2.30

It is now possible to also warp atom positions smoothly e. You only need to install this once if you plan to run qstem V2.

With the fast increase in computer speed that we experience today, it was not my aim to make this code as fast as possible to my shame: Added TEM simulation capabilities. Now no atoms will be removed anymore from the super-cell in softdare by TDS displacements. It should now work better under Windows XP. Fixed a problem with super cell re-centering when tilting in Ncell mode. Fixed improper wave function indexing in TEM simulation code stem3. Fixed a bug in the TEM simulation code stem3.

Matlab Runtime Component Library bit, V7.

Qstem software download

In case the examples folder did not get properly installed on your system you can also download the content of that folder separately. It also qsetm you load images.

Improved imageSim for simulating TEM images from wave functions: The software recognizes no other format at the moment, but I may find some time in the future to add support for further file formats as well.

Simulations with unequal number of pixels in x- and y-direction are treated correctly qtem. In case you have a problem running the stem simulation executing stem3.
