Fig. Overview of VTAnDeM, a software for visualizing the complex interrelationship between phase stability, defect formation energies, and carrier concentration of semiconductors. First principles calculations of bulk compounds and defects are generated by the user a priori. VTAnDeM imports the data and builds a database. It then provides an interactive user interface that simultaneously visualizes the phase stability, defect formation energies, and carrier concentrations.
