OpenMX

OpenMX is open source software that calculates perform density functional theory (DFT) calculations for your class project. You will use it to calculate band structures in this course. OpenMX is installed on the computers in Weniger 412 and you can access from there or you can ssh in remotely from your own computer. Mitchell Senger has written a wonderful tutorial to help you get started. After completing Mitchell's tutorial, you will have produced your first band structure calculation. Once you have completed one example, you'll can find additional information and tutorials on the OpenMX user manual on the OpenMX website.

For calculations for your own material, you will need the position of the atoms in your material. The Crystallography Open Database is one good place to look for crystallography information files (.cif files). A great way to visualize the information in a .cif file is to drag the .cif file into the browser-based OpenMX Viewer. Chrome is the recommended browser for OpenMX Viewer.

For you own calculations, you will need to choose an appropriate path through k-space. This Brillouin zone database is a useful resource. The wikipedia article about Brillouin zones is also helpful for visualizing your path.
