pylada-defects

A computational framework to automate point defect calculations

About:

An open-source Python framework that automates point defects calculations using VASP. Framework creates point defect structures (vacancies, interstitials, sustitutions) and automate computation of point defect formation energy by providing tools to compute finite size corrections (1. potential alignment, 2. image-charge correction, 3. band-filling correction to shallow defects) with the supercell approach. The high-throughput DFT calculations are performed using PyLada.
