WebJan 13, 2024 · The phonopy and phono3py codes are widely used open source phonon calculation codes. This review describes a collection of computational methods and … WebThe calculation of electron-phonon interaction from first principles has recently become feasible using density-functional perturbation theory (Quantum Espresso) [1] and the small displacement method (GPAW) [2]. We determine the strength of the electron-phonon interaction using the Vienna Ab-Initio Simulation Program (VASP) [3] with the small … 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).
