We analyze the leading role of the electron-phonon interaction in promoting the structural distortion from fluorite to orthorhombic FeSi2 by comparing a tight-binding calculation of the force constants and phonon dispersion relations in FeSi2 to the ones in CoSi2, a related compound which is stable in fluorite phase.

Abstract

We analyze the leading role of the electron-phonon interaction in promoting the structural distortion from fluorite to orthorhombic FeSi2 by comparing a tight-binding calculation of the force constants and phonon dispersion relations in FeSi2 to the ones in CoSi2, a related compound which is stable in fluorite phase.
