WebNov 14, 2024 · Dear Phonopy users and Prof. Togo, We are using phono3py (2.3.2) code for thermal conductivity in 2D MXene like structures using LBTE method. First, we want to find the converged q-mesh (NxNx1), so we plotted thermal conductivity with LBTE for N varying from 19x19x1 to 41x41x1 with the steps of 2.

WebMar 27, 2024 · Phonons with positive thermal conductivity are red. The ones with negative thermal conductivity are blue. Phonons with thermal conductivity close to zero are gray. I used VASP and converged all the settings like energy cutoff, k-mesh (for VASP), displacement amplitude (tested 0.03 Å and 0.05 Å) and supercell sizes. http://phonopy.github.io/phonopy/ philhealth online appointment dasmarinas
