Phonon Dispersion Curves
Ref. 3.8 PWSCF calculation. Ultrasoft pseudopotential (Pt.pbe-nd-rrkjus.UPF) has been used, with a kinetic energy cutoff ecutwfc = 45.0 Ry. Kpoint selection: 11x11x11. Energy minimization of fcc Pt yields a lattice parameter of a = 3.925 Å corresponding to the lowest binding energy.
