Abstract
The lattice dynamics of FeSb2 is investigated by the first-principles DFT calculations and Raman spectroscopy. All Raman and infrared active phonon modes are properly assigned. The calculated and measured phonon energies are in good agreement. We have observed strong mixing of the Ag symmetry modes, with the intensity exchange in the temperature range between 210 K and 260 K. The Ag modes repulsion increases by doping FeSb2 with Co, with no signatures of the electron-phonon interaction for these modes.
