In the supercell 2*2*1 there aren't any negative frequencies. I increased the size of the supercell this time. I tried 3*3*1 and I found a negative frequency in order of -8 cm-1 between …
[Phonopy-users] confusion with the units of frequency phonopy
WebThe discovery of active and stable catalysts for the oxygen evolution reaction (OER) is vital to improve water electrolysis. To date, rutile iridium dioxide IrO2 is the only known OER catalyst in the acidic solution, while its poor activity restricts its practical viability. Herein, we propose a universal graph neural network, namely, CrystalGNN, and introduce a dynamic … WebPhonopy calculates phonon frequencies based on input values from users. In the default case, the physical units of distance, atomic mass, force, and force constants are supposed to be Angstrom, AMU , eV/Angstrom, and eV/Angstrom 2, respectively, and the physical … Installation via conda #.

WebDec 2, 2024 · Disclaimer: I have never used Phonopy. The advantage of using DFPT is that in principle it can be used to calculate a perturbation of finite wave vector $\mathbf{q}$ using the primitive cell. This should be contrasted with finite differences, which can only be used to calculate perturbations at the $\Gamma$ point. If you want to access a non … WebCommand options.
