The Phonopy Python package provides a simple interface for extracting vibrational and thermal properties of materials from VASP output. This tutorial shows how to use VASP and Phonopy for phonon density of states, dispersion, and free energy calculations. We will use bulknn MoS 2 2 as an example. WebJul 8, 2024 · Using Phonopy this would be completely impossible, as it would require a supercell of size 110,592 (containing 221,184 atoms)! This calculation is in fact possible (and relatively easy), using nondiagonal supercells, which would only require a supercell of size 48 (containing 96 atoms).
